Alien Hominid Invasion is a spin-off that teams up to four local or online players up in horde mode-like 2D stages. The team will have to complete various objectives while they blast away at never-ending armies of human and robotic bad guys. After completing enough objectives, players race to the extraction point in order to complete the level. After clearing several stages, players will stop at a hideout where they can bank the loot they've found so far and purchase new equipment. Fail a level before then, and you won't get to keep the new stuff you picked up! It's a fun and challenging game structure that encourages replay and cooperation.

From what we can tell, Alien Hominid Invasion isn't a sequel to Alien Hominid. Rather, it's a spin-off that teams up to four local or online players up in horde mode-like 2D stages. The team will have to complete various objectives while they blast away at never-ending armies of bad guys. Roguelike elements and lots of options will add replay value. Based on Steam reviews, it sounds like the game is balanced in favor of co-op, so make sure you have a friend or two to bring along for the action.
