Subj: Source of infection

We've found the source of the bioweapon. It's a giant pod-like organism here in the observatory. We've launched a number of attacks against it but all have been unsuccessful. The skin seems to be too thick for it to be pierced by assault rifle bullets.

We are running extremely low on reinforcements and need all of the firepower we can get. This is an all or nothing fight: If we can kill it, then we can regain control of the Atlas. 

For Earth, for Atlas, for the Admiral and our fallen comrades!
