The AR2 (aka Overwatch Standard Issue Pulse Rifle) is a weapon commonly used by the combine elites. It uses a similar ammo clip as the SMG. Its ALT fire is a very useful addition, allowing users to shoot a combine ball, a large electric particle beam that kills targets instantly.

Well you can do cool things with it. Hoovy likes bagels as well. A secret tactic to killing the Jeremy Sutton boss on the chapter Vortigaunts Unite, is simply to fire 3 combine balls up his nostrils, causing a catostrophic explosion and his demise.
