The Dark Sector 100G
Complete the Game.

---

If you thought the 10 point level achievements were kind of weak, wait until you reap the rewards at the end. At the start you'll have to fight off some soldiers, in which a grenade at the immediate start is useful while they're stunned. The only other encounter is the final boss, which isn't too difficult if you do it right. Three large tentacles will come out, and you'll have to charge your glaive with electricity to hurt them. If they're closed, use a power throw on the nubs to make them open, exposing the eyes. Use Aftertouch to guide the glaive into the eyes, destroying the tentacles, right after the last one is gone quickly swith to your assault rifle and shoot Mezner in the center of the pod and switch back to the glaive when he stops attacking. Another two tentacles will come out, along with zombies that spawn when another dies. Try to ignore them, focusing on the two tentacles and on the last one get ready for Mezner again. The third wave the zombies will be gone, and their will be five tentacles, three in the middle and one on either side of you. Take out the ones on the side first and then the ones in the center. Thats all there is to it, and you'll have beaten the game!
