What is Ratz Instagib?

This first-person multiplayer arena shooter puts railgun-wielding rats in household-themed maps, where one hit can eliminate an opponent. Players aim and rocket jump through deathmatch, team deathmatch, capture the flag, and freeze tag matches.

For you if...

+you like fast, competitive shooters with rocket jumps
+you want team-based PvP matches to play with friends

Not for you if...

−you prefer grounded shooting without aerial movement
−you dislike being eliminated by a single hit
−you want a story-driven campaign instead of PvP matches

What players say

90% of 3,936 reviews are positive

Players praise the fast combat, music, and matches with friends. The most common complaint is that public lobbies are sparsely populated, making matches hard to find; some players also find experienced opponents difficult to face.
