Description
Half-Life 2: Alternis DEMO
created by Echo2056

Date of publish: Jun 1 2025
Synopsis
Half-Life 2: Alternis aims to expand Half-Life: 2's world by introducing new paths and areas to existing levels, and adding some entirely new maps as well, which the player will be able to traverse throughout the game, instead of taking the usual route.

This demo contains the two chapters "Route Kanal" and "Water Hazard" in their entirety, which have all the detours and new areas currently in Half-Life 2: Alternis.
Requirements
  • Half-Life 2 (+ Episode One, Episode Two)
You should mount them anyway, because assets that are included in Garry's Mod doesn't have music or voice-over.
Map List
These maps will overload Half-Life 2 maps. To play this add-on maps, just load maps under 'Half-Life 2' category.

Recommendations
To avoid CTD(Crash To Desktop) or frame drop, please follow these instructions:
  • Use the 'x86-64' branch of Garry's Mod if you are using 64-bit OS (You would already using 64-bit OS).
  • Disable or unsubscribe add-ons you don't use.
  • (only if the game is still broken) Factory reset Garry's Mod.
I didn't experience any frame drops or CTD while testing this map, so if you experienced any, that might be your environment's problem.

I personally recommend you to also subscribe SC Tools for better experience.
Disclaimer
I only test map(s) with Sandbox gamemode with Singleplay environment. I do not guarantee that this add-on will work with any gamemode or Multiplay environment.

I didn't make these maps. I just ported these maps to Garry's Mod. All credits should go to original author, Echo2056.

Resolved it on my end. Seems the 'Bullet Override' addon was the cause. It was forcing all hitscan weapons to be classed as the 'bullet' damage type. I disabled the bullet damage type override setting and everything works fine now.

You can't damage Combine APC in 01a. The Combine APC only takes damage from 'blast damage', and the mounted machine gun doesn't do 'blast damage'.
If you can't damage Combine Helicopter with Airboat Gun, then that is a problem, but not from this add-on.

Was mostly good but sadly a (I'm pretty sure completely unrelated) glitch made the gun emplacements and airboat gun do no damage to vehicles (like the APC and helicopters). If I had to guess, possibly a Campaign gamemode like Lambda Co-op would fix these issues for me.
