Half-Life 2 Substance is back!

The 2005 original is available once again, rebuilt and expanded in an all-new 10th Anniversary Edition.

This mod harks back to a bygone age, when innovation with first person shooters was king.
Games like Thief, Requiem or Shogo would explore new approaches to the shooter genre.
Substance sought to merge the different playstyles into a precursor to the Crysis suit.
Each of the HEV Suit Modes comes with its own weapons and abilities, like energy shields or cloaking.
Just like multiplayer classes, which can be switched on the fly and share one gigantic inventory.



Newly available in this version, is the VR Missions map pack: as Substance used to be limited to the
vanilla and remastered campaigns, it can now be played in over a hundred Half-Life 2 classic maps
such as Strider Mountain, The Citizen, Rock 24, Riot Act and Mistake of Pythagoras!



To install the mod, place the Half-Life 2 Substance Installer in Sourcemods and run it with admin rights.
Note: Half-Life 2 and Source SDK 2006 must be installed, and run at least once before installing.
