This wasn't so bad, but when another team-mate started spamming messages along the lines of "stfu u nigger", the whole situation started getting stupid. My other team-mates protested, and instead of simply sending a message along the lines of "STFU you racist retard", the rest of my team got out their knives and started attacking him.
While we were doing this, a skulk would periodically run into the base, we'd shoot it, and then go back to infighting. So, the aliens got most of the map, and we were buried under a wave of Fades a few minutes later....
