How to Unlock the Predator and Alien Skins on "AVP" for PS3
- 1). Select "Multiplayer" from the main menu to enter the online mode.
- 2). Select "Ranked Match" and wait for the matchmaking process to put you in a game. The screen will then read, "One player in game, waiting for more players."
- 3). Press the "Circle" button to quit the screen, and then select any online Marine mission that contains a high number of enemies.
- 4). Target the more difficult enemies, such as the Praetorian, and defeat as many of them as possible. The harder an enemy is to kill, the more XP you will receive for defeating it. Repeat this process until you've earned 18,060 XP, which will unlock the Real Nasty Habit trophy, as well as all available online skins.
