I must have skipped this level the first time I play this. I'm in the Pharcom warehouses and I've done everything except planet the beacons on the three bodys. But it's only because I can't. Unless the beacons are a separate items that you have to find, the game is *bleep*ed. It doesn't matter how close I am to the bodys or what position I'm in, it won't do it. I scan the bodys, plant the beacons, then scan it again and the computer still says "plant beacon on body". I am way beyond pissed off now, and I refuse to just skip the level. HELP ME! The hell am I doin' wrong?

Well I don't think your game can have an error but when you plant the beacon make sure that your right on top of the boddy or else it woun't plant the beacon.

Make sure you're not using the infinite ammo cheat on the warehouse missions. It won't plant the beacons if you are.
