Voices Of The Void - Not Available on steam but the devs page. And I know it's technically based on UE - BUT IT IS SERIOUSLY UNCANNY HOW SOURCE-LIKE THAT GAME FEELS I mean holy shit. Have a look at it yourself I swear it FEELS so source-y

@Mr. Casual: Thanks mate, I've added those 2. I'll give Deeper Down a short grace period before moving it to No Longer Available.
Mr. Casual 21 Sep @ 10:16pm 
Got a fresh batch for ya:
https://steamproxy.net/steamstore/app/3738640/Portal_Divinity/
https://steamproxy.net/steamstore/app/2121270/Decay_Constant/
Also: Deeper Down's Steam page appears to have been taken down, but it's still available on the HL2 workshop; uploaded by its original developer

Also-also, as a heads-up: Mastercoms, creator of TF2's legendary Mastercomfig, just released all of her mixes for the game as a full-blown mod ("Team Comtress 2"). It's only available on Itch, for the time being — but she's said that it'll be coming to Steam, whenever it's ready for that treatment

jaxx is cool, actually 13 Jul @ 11:38pm 
after some research i just discovered the mod was leaked so i just played it for the last hour lol. sadly it barely has any players so please help populate it if you care to. the only downside is that the only server under 150 ping with players on it that i played on had ear rape end of round music, other than that it was everything i hoped for. just needs more people

@bobm6457: I waited nearly 10 years for it mate. I'm sad too. :proto_raider_sad:
