I started the game up and it truly felt like a quake spinoff, in a good way. However after only... what seemed like 15 minutes in game, I realized that is was made upon the formula of fighting wave after wave of enemeys to unlock the next area (which was, at times, where I was previously). The combat was fun and satisfying, however not very engaging. I held down left click and walked in a circle while having a conversation with a friend and I beat the wave... I didn't have to put any effort into it. If you can get it super stupid cheap, go for it and try it out. maybe you can look past what I see in it.
