This patch fixes Unity's vulnerability CVE-2025-59489, which was published a few days ago. Both the demo and the full game have been patched.No new guns or maps in this patch, but at least the code is now once again as impenetrable as a good killbox with a bunch of flamethrowers and machine guns.More information about the vulnerability:https://unity.com/security/sept-2025-01
- GROSS -- Lunar New Year Festival - 7 February 2024
Hello everyone！ GROSS is now participating in the Lunar New Year Festival 2024. Hope you can enjoy our game!
- 1 year anniversary - 12 January 2024
Hello everyone! It's been one year since GROSS was released, after being in development for over 18 months. I'd like to take this opportunity to thank everyone who gave this game a try, told their friends about it, gave me feedback, wrote a review or sent me some words of encouragement. Making a game is a huge journey and it wouldn't have been possible without you. For the next two weeks, GROSS is 50% off. If you already own it, it makes an ideal present for in laws, new neighbors or as an ice breaker on first dates. And if you downloaded it from The Pirate Bay, now's a good chance to clear your conscience. What have I been doing lately? One of the most requested features for GROSS has been co-op multiplayer, so I've spent the last couple of months learning the core concepts of networked multiplayer. I don't like learning in a vacuum though, I need to learn with a clear goal in mind. Wh…
- Patch Notes 20.04.2023 - 20 April 2023
Bug fixes ATMs that were glooped didn't pick up existing cash once the gloop was gone. Small bug/performance fixes. If you encounter a bug, please report it straight away ingame by pressing F1 and describing the issue. This makes it a lot easier for me to replicate and fix it. If you would like any direct feedback, don't forget to include your email address.
- Patch Notes 10.04.2023 - 10 April 2023
Hello there, It has been a while since the last update. It's another relatively small patch, but I hope it will make the game a wee bit better nonetheless. Features & other changes Highscores now display the wave that players reached (this only works for highscores recorded with this and future versions of the game). There is now extra score awarded at the end of each combat phase, based on how much health your base has left. The score you receive is 10 * * . A few examples: If your base has 87% health left at the end of the 5th wave, you get 4’350 extra score. Over 10 waves, you can gain a maximum of 55k extra score. Over 20 waves, you can gain a maximum of 210k extra score. Over 30 waves, you can gain a maximum of 465k extra score. The score is awarded right when the last zombie dies and the 10 second grace period starts. The score is added directly to your total score and is not subj…
- Permanent "discount" - 14 March 2023
Hi there, The base price for GROSS has been reduced among all currencies, by roughly 25%: $17.99 -> $12.99 £14.99 -> £10.99 €17.49 -> €12.79 etc. Prices in Turkey and Argentina (areas where the recent recommended pricing changes from Steam hit extra hard) have been reduced by about 50%: TL 175 -> TL 90 ARS$ 1,300 -> ARS$ 650 There has never been a better time to get a copy of GROSS! If you read this before the 16th of March, you might want to hold on a little longer though...
- Patch Notes 01.03.2023 - 1 March 2023
Intro Hello there, This is a quick interim patch, mainly to ship the new Spanish language option (a huge thank you to Julio Duran) as well as a few bug fixes. Features & other changes Spanish language option added (a big thank you to Julio Duran!). Bug fixes Fixed a bug that prevented the shotgun from aiming down sights after it was reloaded. Mannequins in HOME were not targeted by smart rounds. Fixed a bug that sometimes caused zombies to spawn for 1 frame with a red outline. Fixed a bug that made it possible that hologram decoys sometimes activated in mid air. Modifiers (player speed, base health, etc.) are no longer displayed in the end game screen after a game in story mode (where modifiers don’t apply). The turret controllers laser now looks more like a laser instead of a plastic stick. Balancing SMART rounds are now more consistent and are no longer based on the type of bullets th…
- Patch Notes 27.02.2023 - 27 February 2023
Intro Hello there, This patch mainly works on performance issues. Frame rates should now be a lot more stable at later stages. There are still a few things left to do which will follow in later patches. Coming soon The next patch will focus mostly on minor bug fixes, and will also include one or two bigger feature changes. Which ones, I haven't yet decided. (wow, what a helpful paragraph this was!) Now off to the actual patch notes: Performance SHOTGUN, OH DEER, DEAD END, CONFLICT, BULWARK: Reduced polygon count by about 25% (millions of triangles sacrificed their lives for better performance), mostly by reducing vegetation. Other levels: Reduced polygon count slightly. Optimized path finding to take load off the CPU. Many other small tweaks to optimize performance. Frame rate increase (depending on level, situation and hardware) between 10 and 50%. Features & other changes Changed the…
- Patch Notes 28.01.2023 - 28 January 2023
Intro Hello there, This patch took a bit longer than anticipated, and I apologize for that. Apart from the bug fixes, it addresses two major issues that players (understandably) have with the game: The story mode is too hard. The game forces players to play the story before letting them play endless mode. Both these issues are based on decisions I made that haven't been fully thought through. I hope I'm rectifying them with this patch. Otherwise please let me know below or via in game feedback. Coming soon I'll try to add this coming soon section to the patch notes from now on so that you know what you can expect from the patch after this one. The next patch will include a few more bug fixes but will mostly be focused on optimizing the performance. Now off to the actual patch notes: Features & other changes A new main menu with the following options: Start/continue the story, and experi…
- Patch Notes 17.01.2023 - 17 January 2023
If you encounter a bug, please report it straight away ingame by pressing F1 and describing the issue. This makes it a lot easier for me to replicate and fix it. If you would like any direct feedback, don't forget to include your email address. Bug fixes & performance improvements Performance improvements with impacts (blood, concrete, wood, dirt etc). Limited the amount of simultaneous blood impacts (the blood splatter particles when you or a turret shoot a zombie). If you’re going bananas with machineguns and nailguns there are LOTS of impacts everywhere. Performance improvements to ragdolls (makes a big difference in later waves). When dying from green gloop while transitioning from combat to construction phase, the green overlay remained and did not disappear (obviously only if you had a respawn point, otherwise it’s good night anyway). When reloading an endless mode game, the respa…
- Patch Notes 13.01.2023 - 13 January 2023
As always: If you encounter a bug, please report it straight away ingame by pressing F1 and describing the issue (my crystal ball is currently in the dry cleaners). This makes it a lot easier for me to replicate and fix it. If you would like any direct feedback, don't forget to include your email address. Bug fixes It's no longer possible to activate the car in the intro level twice (which leads to the second level not loading properly, which in turn means no zombies spawning). The achievement for completing CONFLICT in story mode is now correctly granted. If you have already beaten this level, the achievement will be granted automatically the next time you start the game. The white Jeep in SHOTGUN had no collider, which allowed you to walk/shoot straight through it (thank you wessubba you weirdo). When adding your name to the local high score list, it's no longer necessary to type at l…
- Launch & known issues - 12 January 2023
Hello everyone, First I'd like to thank everyone who picked this game up and gave it a go. A lot of energy has gone into this game, and I really hope it shows. Also big thanks to everyone who reported issues, you are actively helping to make this game better and more enjoyable for everyone. Talking about issues: There are a few bugs in the game currently, with the most serious ones being: It's possible that the second level (the first proper tower defense level) doesn't load properly. You can tell because the UI isn't cleaned up (there's a score hanging around the top) and the will not be any zombies spawning. This happens when you activate the getaway car at the end of the intro levels twice, which trips up the level load. Workaround: Restart the game. You can get stuck at the scoring screen. If you enter fewer than 3 characters, the game doesn't let you leave the input field. This was…
- Patch Notes 09.01.2023 - 9 January 2023
As always: If you encounter a bug, please report it straight away ingame by pressing F1 and describing the issue (my crystal ball is currently in the dry cleaners). This makes it a lot easier for me to replicate and fix it. If you would like any direct feedback, don't forget to include your email address. Bug fixes There were instances where zombies could get stuck in places where they couldn't be seen or shot by the player. This was keeping players from killing the last zombie(s) and progressing to the next wave.
- Patch Notes 08.01.2023 - 8 January 2023
As always: If you encounter a bug, please report it straight away ingame by pressing F1 and describing the issue (my crystal ball is currently in the dry cleaners). This makes it a lot easier for me to replicate and fix it. If you would like any direct feedback, don't forget to include your email address. Bug fixes It was possible to build a turret or barricade in an invalid spot by very quickly moving over from a valid spot and pressing the construct button. Exploiting this made it possible to keep enemies from reaching the base, therefore removing any challenge from the game. Sometimes zombies from the credits found their way back to HOME. Zombies from the credits are now disposed of in a humane and eco friendly way.
- Patch Notes 07.01.2023 - 7 January 2023
As always: If you encounter a bug, please report it straight away ingame by pressing F1 and describing the issue (my crystal ball is currently in the dry cleaners). This makes it a lot easier for me to replicate and fix it. If you would like any direct feedback, don't forget to include your email address. Features The camera FOV (which affects the world, but not the gun) can now be adjusted between 60° and 120° horizontally. Default is 85° (which was the fixed FOV up to now). Bug fixes When you shoot incapacitated turrets with the deglooper, sometimes the bubbles remained. While this indicates a level of cleanliness that is desirable, it can give the impression that there's still some kind of effect when in reality it was just a programmer not testing it properly. This is now fixed and the person responsible has been whipped thoroughly. Balancing When Big Gloops explode, the radius in w…
- Patch Notes 06.01.2023 - 6 January 2023
As always: If you encounter a bug, please report it straight away ingame by pressing F1 and describing the issue (my crystal ball is currently in the dry cleaners). This makes it a lot easier for me to replicate and fix it. If you would like any direct feedback, don't forget to include your email address. Bug fixes Slightly moved the player spawn points in a few levels to make sure you don't spawn in the middle of a barricade or turret when reloading an endless mode savegame. The difficulty you set inside the RV during story mode is now always applied correctly. The Cy Ka 47’s bullets were hitting a little bit lower than the spot where the iron sights aim at. This is now fixed.
- Patch Notes 05.01.2023 - 5 January 2023
Another small update, probably the last one before release (just like the previous one, remember?). As always: If you encounter a bug, please report it straight away ingame by pressing F1 and describing the issue (my crystal ball is currently in the dry cleaners). This makes it a lot easier for me to replicate and fix it. If you want any direct feedback, don't forget to include your email address. Bug fixes Performance optimizations that should greatly reduce the performance hits in later game stages with lots of turrets and enemies. Nailgun turrets no longer attack Ghosts while they’re cloaked. Changes/Features/Balancing Reduced the extra health that enemies receive in endless mode past wave 20 significantly. I know at least one person who's going to be very happy about that. Capped the tremor boots ability to double jump to a certain height. Buffed the Fat Bertha (cannon) to account b…
- Patch Notes 14.12.2022 - 14 December 2022
Another small update, probably the last one before release. Unless I added a big bug. Fingers crossed I didn't. Bug fixes Performance optimizations. Fan and ATM turrets were not always affected by green gloop anymore. The first one or two sticky grenades thrown in each level did not spawn properly. The players bullets sometimes did not hit zombies that were very close in front of them. Changes/Features/Balancing New gun attachment: The Deglooper. Like the cash pickup attachment, the Deglooper can be toggled on and off. When switched on, bullets are covered in a soapy gel that rapidly dissolves green gloop that’s disabling your turrets. Every time you hit green gloop with such a bullet, the decay rate of the green gloop is doubled. This effect stacks infinite times. Usually, gloop decays over 30 seconds (or you can shoot it to take seconds off). If you hit it 4x with the Deglooper, it de…
- Patch Notes 01.11.2022 - 1 November 2022
Once a gain a small update only, while I keep working on the levels and the progression system. Bug fixes Chinese characters were not displayed correctly in the highscore list. Colors in scope sights have been improved. Fixed a few level boundaries in SUMMIT (available in extended Demo only). Changes/Features New equipment icons. Achievements have been added to the demo. Texts in constructible object selection are no longer rotated 90°, as my contract with the chiropractors guild has run out and there is no longer any incentive for me to hurt your neck.
- Patch Notes 22.09.2022 - 22 September 2022
I'm currently working on the remaining levels, but here's still a little something that I hope you'll enjoy :-) Bug fixes Shooting at hologram decoys did no longer cause them to glitch. This is now fixed and shooting at hologram decoys is now sufficiently satisfying again. (This includes the one in HOME, so have fun with that). Melee attacks no longer affect more than 1 zombie. Changes/Features New game icon. There is now a dog in HOME, doing dog things like sleeping, sniffing and pooping. You can even pick up and throw balls. Why is it there? How did it get there? Does this mean anything? If you want to know the answers to these questions, you only need to to wait until January and experience the story of GROSS.
