Soap in City 17

Play Half-Life 2 as a Call of Duty 4 soldier.

A loadout screen opens first: choose a primary (M4A1, AK-47, MP5, M1014), a sidearm (M1911 or USP) and your grenades. Then you deploy into City 17 with your kit, and every shot sounds like Call of Duty 4.

What you get

• A "Create a class" loadout screen before every run
• Your chosen weapons, suit and ammo handed to you on spawn in City 17
• Gunfire read from your own Call of Duty 4: Modern Warfare (2007) files each time you play

What you need: your own copies of Half-Life 2 and Call of Duty 4: Modern Warfare (2007). Nothing from either game is included in the download.

Notes: single player only. Weapons keep their Half-Life 2 models; only the gunfire comes from CoD4. If your loadout hasn't arrived a few seconds after you spawn, press F9. The mashup uses cheat commands to hand out your loadout.
