The '''OICW''', also known as '''AR2''', is a weapon cut from ''Half-Life 2''. It can be found in the Development of Half-Life 2 game|''Half-Life 2'' leak. It was to be used by the Conscripts (later Resistance|Rebels) and the Overwatch Soldiers,WC mappackDevelopment of Half-Life 2 game|''Half-Life 2'' leak to be replaced in the final game by the Overwatch Standard Issue Pulse Rifle.

In the ''Half-Life 2'' leak, the OICW, based on the real-world WikipediaXM29 OICW|XM29 OICW by Heckler & Koch, is essentially an OSIPR with a scope and a built-in WikipediaGrenade launcher|grenade launcher instead of the energy ball thrower. Its recoil makes it very difficult to control past five shots in a row. However, this can somewhat be reduced by crouching.

It uses medium rounds, which are also used by the AK-47, the MP5K, and the MP7.

In real life, the OICW features a grenade launcher. While not working in the leak (it is in the source code, but is disabled), it was shown working in promotional videos. It appears that its grenade function was moved to the SMG1 by the time the files were leaked, as getting close to the SMG grenades in the Development of Half-Life 2#WC mappack|WC mappack map "zoo_item" causes the message "AR2 Grenades" to appear on the screen.Development of Half-Life 2#WC mappack|WC mappack

Interestingly, the scope on the OICW when unzoomed is broken in-game (it shows a solid light green instead of the scope texture), while it works properly when viewed with the leak model viewer.

Screenshots featuring the OICW in ''Half-Life 2 Raising the Bar'' show an early model with a texture that made it look very damaged and used-up.''Half-Life 2 Raising the Bar'' This texture is still in the leak files, as seen .Development of Half-Life 2 game|''Half-Life 2'' leak files

The retail MP7's grenade model is still named "ar2_grenade.mdl".

In the final version of ''Half-Life 2'', the Rebel's reload animation for the AR2 Pulse Rifle is the same as the OICW's in the leak.

In the ''Half-Life 2'' files, several texture files for HUD weapon icons can be found, most of which still containing the icons for almost all of the CategoryCut weapons|cut weapons. The OICW is among them. It is also present in the font "HalfLife2.ttf", used for all the HUD glyphs.
