I am currently stuck in the second part of the final mission: The Endboss already came down to the ground, wielding shield and gun and there are LOADS of enemys. In the beginning Lannis says to split up and take them out on two routes, but I just stuck together as a team, connected the floating islands to the main island and let the enemies come to the starting point. All my characters are in full cover, #13 is beaming around the crates and dispensing the healthpacks he finds. I always get overrun. What do you guys do? Stick 13 in the prototype tank and have him block the path? The problem is that the enemy aims much better, even than all my level 10 aiming characters. Grenades do nothing anymore. Anybody want to share some tactics?
