Call of Duty 4: Modern WarfareEdit
In Call of Duty 4: Modern Warfare, radiation zones are seen in the campaign missions "All Ghillied Up" and "One Shot, One Kill". When the player enters the zone, their movement becomes sluggish and their screen begins to fuzz, and eventually the player is killed unless they leave in time.
Call of Duty: Modern Warfare 2Edit
In Call of Duty: Modern Warfare 2, radiation zones appear in the multiplayer levels Afghan and Wasteland. Their effects are similar to those from Call of Duty 4: Modern Warfare, except blood appears on the screen. The radiation zones also appear in the Special Ops mission Hidden, which in turn is based on "All Ghillied Up".
- On the rare occasion, if venturing far into a radiation zone, sights will fade away and then reappear, as if blinking.
- It is possible to get out of the radiation area using Painkiller without losing any health. However, the screen 'blinks' making visibility low.
- The enemies in "All Ghillied Up" can walk in the radiation zones and not die.
- These replaced the Minefields from previous Call of Duty games.
