The Technomancer

First of all before you start the game. You me want to play mars war logs since thats the game before this. Okay lets begin. First of all once in the training area you may want to grind the weapon achievements and get used to combat. Once done continue through the story. Try and dodge enemy attacks and keep your distance. After a while you will reach the arena. Before going down the ladder save. This a boss fight. You best use rogue. Attack the bug belly when you can to deal max damage. Other then that avoid the bugs and stay behind the boss its safer. Once back at base you be told to find a merchant. Before you do that report to the captain to fain help. Make sure you do the deserter mission first so you don't miss it. The rest of the chapter is simple mostly. Make sure to speak to scott in the slums and do his missions. Same goes for Jeffrey and then the rover driver once available. I hope this helps.
