Surface Tunnel

A nice break from the usual combat now, and we get to ride on board and control Rex. Press X to swing around and take out enemies nearby (they will slow you down if you let them get to close). You get three weapons in addition to this. A laser, gatling gun and missiles. Switch between them as you would with any gun. Staying still for too long will see you receive too much damage, but the whole area only really takes a couple of minutes to get through, so destroy as many enemies as you can for the all important Drebin Points. There is no way to repair Rex however, so don't feel you have a licence to take damage as and when you like – you may well be skating on thin ice by the end of the level. Follow the route to the end corridor.
