Aliens: Colonial Marines - Pulse Rifle MK2

This weapon is the standard weapon in the game. You'll start out with this weapon and find use for it for a good portion of the game. It carries 40 rounds in a clip and is capable of firing at a good speed. It doesn't excel in any one area but it is better than average in most.

To add to the Pulse Rifle's versatility, several types of alternate fire can be added to the weapon. There are two types of grenade launcher (one of which launches Firebombs) and a twelve gauge tac-shotgun.
