Call of Duty and Portal Crossovers
Portal 2 Hell by Omega the Omniscient reviews
([It's been too long! In case I never come back to this, chapter 7 is a very rough outline of what would have been]) GLaDOS has been testing things other than portals in the Enrichment Center. Things have gotten out of control, and Chell's involvement with a certain resistance group is about to bring her back to the hell she thought she'd left for good. T for language/violence.

Zombification Order by redsquidz
GLaDOS has a new set of tests to run - namely, seeing how the portal gun can be used alongside actual weaponry in the event of a zombie outbreak. She's combined several testing chambers into one large testing arena and, much to Chell's annoyance, released swarms of zombified scientists (looks like all those corpses from the neurotoxin event came in handy!).
