its no secret that Portal is in the same universe as Half-Life..... so i was wondering, where does Portal and Portal 2 take place in the timeline, before HL 1, After HL2, between them, etc.??
does anyone know
did i miss anything, has valve ever elaborated on the relationship between the Combine and the Xen...
- Did the Combine and Xen know of each other before the events of Half Life 1/the resonance cascade/ black mesa incient
- Was the Combine in control of the Xen during the black mesa...
