More multiplayer progress #3 — Quadrablaze Steam update #124700

This may be the second-to-last update before I take it out of the multiplayer_test beta branch. Afterwards I'll start working on more abilities and weapons. Also more enemies will be added afterwards. Changes New internal ability/weapon code to make it easier to create new ones! The red explosive enemies now do damage to anything nearby instead of just who touched them Enemies spawn in random locations around the arena instead of in a clockwise loop Free Trinity boss spawns outside of the arena
