PREQUEL: PLAY AS THE ALIENS, as they invade Black Mesa! Play through the invasion as any creature you can choose that are from Xen! NOTE: You wouldn't be able to choose zombies, you'd have to be a headcrab and zombify them.

Sequel: After the death of ***, You and Alex travel to the Borealis to find Judith. But with the Combine...

(important note: NOU DONT SAY "COMBINES" UNDER ANY CIRCUMSTANCES EXCEPT WHEN TALKING ABOUT THE DIFFERENT TYPES. WHEN TALKING ABOUT THE COMBINE IN GENERAL YOU SAY COMBINE AS THE PLURAL! And sry for grammer mistake =D)

... away, the Xen creatures are here to stay...

TELL ME WHAT YOU THINK =D
