- Steam Next Fest: Core 2025 Challenge - Play the Demo and win a Steam Key - 13 June 2026
Next Fest is officially live, and Sphere TD is launching into Steam Early Access on 25 June. To celebrate, I am hosting a challenge for anyone who loves deep strategy, optimization, and perhaps a bit of self-inflicted theorycrafting pain. The Galatium Academy Final Exam If you can conquer the entire core campaign in the Steam demo, you get the full game for free when we launch. But be warned: this is not one of those casual tower defense games where you plop down a generic archer tower and go make a sandwich. Map 50 is a brutal, hand-crafted final exam that will test your routing logic, your grid packing, and your projectile math to their absolute limits. The Reward. A free Steam Early Access key when the game launches on 25 June. The Catch. Keys are limited, and we will be issuing them to verified completions while supplies last. The Rules. You must complete all 50 Core 2025 maps with…
