Megaerathia: i have some instagib maps uploaded here (these maps represent the instagib gametype known from ut or q3), and i use marine-based models in them. I think this model is very good, and since i'm planning to update instagib maps as soon as i get enough feedback, i'll probably import this model as well. Actually i have DLed it, and i was the on who rated it 5, but i haven't taken a look at it (how lazy am i), but as i can see from the animation names it has marine animations, so it will perfectly fit into my game. Of course i'll give creidits, i always do that.
Megaerathia: A map where you play a marine and stuff. Also the name for a mutator for UT that comes with the game, where you wield a deadly rifle that kills anyone in one shot (1).
Better! This one could be used as a 1 stage harder monster than your first one.
