After you find a ship you need to find a warp drive to get out of orbita nd visit other plantes. Head back to the cosmodrome and finish what you started. Grab a warp drive and head off into deep space to take to the fight to them! When you land, go in search of parts to salvage. you will find a map and fight some bad guys, but the real fight happens at the end when you fight the Devil who climbed out of the wall after you took the ship. Take him down with shots to the head and be sure to dodge his gun blasts. Kill the adds and never ever get close to him. Keep moving and keep making headshots to take him down faster. Keep an eye on your grenade cooldown as well and use it as often as you can.
