Critical Impact | Alien Shooter - Revisited | Mission 09 [All Secrets]

Mission 09:
Critical Impact!
Description:
Prepare to enter the last levels of the lab complex. This appears to be where the infestation originates. Find the creatures. And destroy both them and their teleporters. Give them my regards when you send them to hell.
Tips:
To destroy the teleporters you will need a lot of explosives. Locate it as quickly as possible or all your efforts will be in vain. Elimination of these teleporters is essential or else they will simply spawn a new army of creatures. #sigmateam #alienshooter
