This mutation was once a stolen item but has since been transferred under the correct author's ownership, thanks to the courtesy of Gamemaps. For user convenience, I'll leave this file up for download and as a redirect point to my updated version of the mutation, "Beta Mutation Official". As such, this page will no longer receive updates.

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...
