Half-Life - Residual Point - Upper Yard - Course To Lambda - Into The Portal
0Residual Point (2004-2007, 2020's last update). You’re W Jack Sohn, a PH D. MIT Theoretical Physics Decided Major, Research Associate at Black Mesa Biodome laboratory. The story is set on HL1’s official or maybe alternate timeline. Resonance Cascade occurs and once again you have to fight your way through the alien invasion. These are the 2007/2008 original (1.0) version + the last maps/chapters "Residual Point" and "Final Escape", with my own saved games. To reach the last maps : at the red teleporter ("Dread Plot" chapter), there are now 2 purple crystals on the rear face. Shoot them both. Then step into the teleport and instead of triggering the original ending, you will go to "Residual Point" chapter.
11) UPPER YARD : countless fights in classic Black Mesa rooms, harder than ever.
12) COURSE TO LAMBDA : short and action-packed final part before Xen.
13) INTO THE PORTAL : Lambda Portal + Xen-like level
