Post news RSS UT3 Invasion Alpha Demo

The first release of the UT3 Invasion Mutator by RBTT! This version is preconfigured with 8 waves and 7 monsters displaying the possibilities of just the wave configuration.

This is a demo version, this means it is not configurable. We did this because it's stable like this, and we couldn't wait to get responses from players. It's fun to play nonetheless!
