Half-Life 2 Substance is back!

The 2005 original is available once again, rebuilt and expanded in an all-new 10th Anniversary Edition, thanks to the support of our community and the crews of System Shock Infinite and SMOD Standalone.

Half-Life 2 Substance installer v2.1
Half-Life 2 Substance full version

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!

VR Missions Final

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.

I love MGS and I love this mod, it's a weird mashup but it works. The only problem is how underpowered Big Boss is, the cloak takes so long and with HL2 being a linear affair, nobody's going to come up to you, it only serves to take you out of combat for a second, which isn't how camo worked in MGS 3. I recommend making it work for him only if he walks, but work indefinitely. And if anyone should have a CQC weapon, it should be Big Boss. Snake is way overpowered and Raiden is a little on the weak side, I also haven't been able to execute his lunging attack.

thanks it worked.

I love the crosshair, that it turns invisible when moving and visible when standing still.

The mod is amazing and I have played the old version many years ago so I have to complain about this:

1- Old voices when suit switching were better.
2- No Gray Fox,
3- Old SMOD tactical Slow Mo effects were a lot better, especially the orange bullet trails and the head shot effects.

Really those are my only complaints and like I said earlier, EXCELLENT MOD

This might be obvious but, Why does ripper mode lose health when not in stealth and when no one is nearby?

It used to be an unlockable OP class, trading mad damage for the need to stay hidden (invisible or crouching). It's unlocked from the start but slightly nerfed now, best used in short bursts.

The new installation files are up. First you extract them in Sourcemods, then you either run the installer or move over a file manually.

Been a long time since I played this last. So I thought I would give it a play this weekend for a couple of videos.

Good times.

Back in the golden days of hl2 modding, this was something I played multiple times, and looking back at it, I sincerely wish I could go back for more :( The new additions to the hl2 campaign struck me with surprise and awe and the dozens of new weapons made the action tight and refreshing, with new additional monsters and player abilities to decimate them with. It's a shame this only partially works with mod fixes following the may 2010 update. Perhaps someone with some free time on their hands…
