Hints & Tips

Secret War: D3/AU Semi Auto Sniper
In order to get the D3/AU semi auto sniper rifle in the Secret War mission, go inside after Uri blows the door. Then wait until the commander asks you to return the bunker room and turn on the generators for the building. Once he does, go outside then instead of going to the bunker, turn left when you leave. Go up the ramp and search around at the top of it for the sniper. Note: It is behind a few of the boxes up there.

Secret War: Extra secondary weapon
In order to get a extra secondary weapon in the Secret War mission, simply follow the troop that moves above the place close to your commander and troops in the upper right. When you get there, search around and you should hear your commander say "It's quiet, too quiet". Then, search for boxes that you can climb on. When you locate them, jump up. You should now be able to jump onto a ledge then walk along the ledge to find a pillar that you can also jump on. Once you get on the pillar, look around on the ground. You can find two pistols, which are dual elites. Jump down to grab them then look in the crates close to where you got the pistols. You should find 9mm ammunition for them.

Secret War: Grenades and ammunition
When the other soldier picks the lock, reach the bunker. Turn right and locate a terrorist. He should be dead. Now search around the big boxes. You should find a few He grenades and 9mm ammunition.

Downed Pilot: Guns and armor
Soon after you have rescued the first pilot, go into the room where you planted the first RC bomb. Blow the wall up. Go in the room and take out the terrorist in the room. Look at your surroundings. Notice there are ammunition crates stacked up leading to a vent. Just beware, before you go into the room if you are low on health use the medi kit on the wall in the hallway. There are two terrorists lurking in the shadows in the corner behind the armor crate. Once you take kill them, get the M4A1 carbine, the Leone auto shotgun, and the armor.

Get rocket launcher in every mission
First enable the weapon_laws code. It is in the item category. Note: It is suggested that you not  use this code after your player has shot the laws and did not drop it. If you have enabled this code while the player is dropping the laws, you will not be able to use the cheat again until you restart the mission or reload. Wait until your player drops the empty laws and auto switch to your primary weapon, then type give weapon_laws again.

High Rise: ES C90 and ammunition
Once you go into the building in the second room after your commanding officer informs you about the civilian contact that is awaiting you, the door to the next room is opened by four terrorists. Now kill them all then look around the room where you got the order from your commanding officer. Search for the fire extinguisher next to a set of doors that will not open, but you can go inside. Shoot the fire extinguisher. Note: The fire extinguisher will explode stand back to stay unharmed. Now duck then jump into the hole and go in the room. Inside you will find by the desk in the back an ES C90 and some ammunition.

Get Counter-Terrorist or Terrorist weapons
If you do not the money to buy a good weapon, buy some Kevlar and a pistol. Then, either kill a Counter Terrorist or Terrorist and pick up their weapon and scavenge one from their dead bodies or take it from one of your teammates when they die in a fire fight.

When you have a weapon that you do not like and you see a Counter Terrorist or Terrorist with a weapon you want, kill them with your weapon and press G to drop your weapon. Then run over and pick it up. Noemally the CPU or player with the gun has ammunition for it.
