When you kill a certain amount of players in Player versus Player Mode, you can choose from the following...
This deploys a UAV (unmanned aerial vehicle) that shows the enemies on the radar as dots. The UAV can be shot down by the enemy.
Care Package Description: Drops a package that heals for 100% hp & mp.
Sentry Gun Description: Airdrops a place able XM312 Sentry Gun that will automatically fire at enemies. It cannot be destroyed by any means. The Sentry Gun has a full 360 degree turn on its turret and can pitch up and down. You can move the Sentry Gun around even after you've deployed it, but it won't fire until it's placed.
Predator Missile Description: This allows you to remote control a Predator missile. After opening the laptop, you have approximately 5 seconds to control the missile to your target, as it goes down. You can also give the missile a boost to make it go down faster.
You are vulnerable while using the Predator missile, but if you get killed, you can still continue to control it.
Attack Helicopter Description: Deploys a helicopter to the battlefield like in Call of Duty 4. It will circle the map and automatically attack the enemies for a few minutes and leave. It can be destroyed with guns and missiles.
Pave Low Description: This deploys a heavily armored Attack Helicopter (Sikorsky MH-53 Pave Low) to the map for maximum carnage. As with the Attack Helicopter, all the kills are added to your kill count.
AC-130 Gunship Description: After the AC-130 Gunship is deployed via laptop, it will enter the map. You control it remotely for 30 seconds and you can use the 25mm, 45mm and 105mm guns to shoot at enemies. You are vulnerable while controlling the AC-130, but if you get killed while using it, you can still continue.
Note: The AC-130 can be shot down by the enemy, but it does have flares as countermeasures.
Tactical Nuke Description: Gives you and your team an instant win. The Tactical Nuke ends the match with a bang by killing everyone on the map.
