Classic AVP 2000; skirmish mode, 4 minutes; trapped, marine; man, those bugs sure love to zerg-rush!

Well, a bit less of a pain than Hive at least, but still not very good for a chokepoint or more range in line of sight; the smartgun once again is simply awesome, even though the placement of its spawn point is a bit far from the most useful place to stand one's ground against the swarm of doom.
