Half-Life - Residual Point - Dread Plot - Residual Point - Final Escape
2Residual 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.
14) DREAD PLOT : based on Interloper but it's a "Zgrunt" factory. There is a Xen-themed tram ride, and the only boss fight of the mod (2 Gonarchs).
15) RESIDUAL POINT : You are back on Earth on a 2nd Surface Tension-like level but the skybox is now like Xen's.
16) FINAL ESCAPE : Surprisingly short final chapter featuring the last fights before trying to flee this mess - for good.
