I'm guessing this game uses LAN because P2 uses a PS or Xbox controler... You should make it so you can invite friends into it useing diff Wi-Fi points

It isn´t online. You play on one computer, with the navigator using the mouse to open doors and his or her voice to guide the other player (via the in-game audio feedback). Player two moves with a connected xBox controller (left stick bas back and forth, right stick as steering). The recommended blindfold and soundproof earphones are just for atmosphere.
This does in fact mean that in order to play, you have to get a friend over to your house.
