EDIT: Spitter Pods DON'T give XP. I was gonna make them give some each, but I've been making so many of them it would've been way too easy for you.
You move down. Devie fires at where she thinks pods might be through the wall. You continue down and open fire on all enemies you see.
Devie's wall-breaking blast wounds the first large alien, and the firepower of your troops takes it from there. The pods on your eastern side burst.
(Devie's okay, I just left the cursor on her when I took the pic)
You continue firing. Devie annihillates the entire lower half of the second beast, killing it instantly. The Spitters are also dealt with as well, but there are more pods on the other side that could burst any minute.
Alien Warrior Killed! 50 XP!
