To play Custom Mutations online, they'll have to be played via a Local Server. If you have my Singleplayer Enabler mod (linked below), you can play 4-player Mutations in Singleplayer!

This mutation is like Tank Rush with a twist: There are only boomers at first, but boomer vomit will attract a mob of tanks. The goal: finish without getting vomited (and if you do get vomited, finish without dying). It may sound simple, but as you will see, it's harder than you think. On a scale of 1 to 10 difficulty, this mutation may get a 9/10 difficulty! Play with friends. Not for the fain...

A little mutation idea we had while playing Tank Arena with friends. Bar the route of other players so they get mobbed by tanks or simply burn your friends to death. Last player alive scores 1 point. Guns don't deal damage to players, only molotovs do. Fire deals the same damage in all difficulties (Expert damage). Only temporary health is allowed (Medkits and defibrillators are removed). ...

This mod aims to fix that, and make a mutation suited for those lone wolves out there. I hope you have as muc...
