Bad Rats is a competitive co-op shooter with great depth. The weapon progession system is intuitive and enjoyable. I always look forward to logging on and levelling up my rat. There are four different rats. Fat rat, small rat, good rat, and bad rat, with Bad Rat obviously being the last unlockable character. I don't mind the character unlocking process but I wish it didn't take 200+ hours to unlock the most powerful rat type. The graphical aesthetic is pleasing and it runs as smoothly as source. Some of the game's advanced mechanics are difficult to grasp, such as no-scoping and 360 degree turns, but otherwise it's a simple game that is difficult to master.
I look forward to exceeding 500 hours in Bad Rats.
