Ok, a lot of people have gotton really **** at me for doing this, but i don't really think that its a bug or anything. On eclipse. if the alien hive is the eclipse hive u can really effectively spawn camp them and basically shut down all respawns until you run out of ammo. As a lone marine early in the game, if u can manage to make your way to their hive without getting killed on the way u can just sit in the back corner and unload on each skulk as it spawns. Usually i can manage to get to their hive 1/3 of the times i try. Sometimes i get waylayed by building stuff or get eaten by a skulk. But once im in there im almost impossible to kill. From the back corner of eclipse, the side opposite the resource node, you can see every spawning alien. Theres one spawn point thatll be really close to you, make sure not to stand on it. and don't bother shooting the hive, that'll just waste your ammo and you'll get killed between reloads. If the com is watching over me, it can mean that we win the game right there, sometimes get a few other marines to help. Some people say don't spawn camp, but isn't that exactly what the skulk rush is? They spawn camp the infantry portals and eat any marines that come out early in the game.
