Multiplayer Beta Release Q1 2014 Cancelled

Our plan to bring you the multiplayer beta of Operation Black Mesa early this year didn't work out, regrettably. Several factors and circumstances forced us to completely keep it under the hood until further notice.

Multiplayer Progress

Multiplayer will feature classic maps such as Yard, Crossfire and Boot Camp as well as brand-new ones like Deptcharge and Gambit from day 1.
Currently in development: CTF mode and weapon placement.


Singleplayer Campaign

Development is running smoothly; those NPCs aren't going to animate themselves though! If you're interested in joining our team, check out the jobs page where you can find all positions currently open. We look forward to welcoming you on board!

Pit Worm's Nest

Remember Guard Duty (Blue Shift: Source)? We're making solid progress here too:

Living Quarters Outbound

OBM: The Video Game?

We've been given the option of developing our projects as full indie titles to be sold on Steam!
This opens up a whole lot of attractive possibilities to consider; however no decision has been reached yet as to this matter.

Alien Controller

M1A1 Tank

Thanks for your support in making all of this possible!

Until next time,
Tripmine Dev Team

Question - will you guys have a FarCry style weapon system where you can only hold 4 weapons at once?

IMHO that method works really well if a game has a huge arsenal like OP4 (and you guys seem to have expanded the arsenal) particularly since limiting the player to 4 weapons saves them spending ages scrolling through their HUD to find a weapon.

No sir, we are going to stick to the HL weapons selection system :)

Well, the main reason I ask is that you guys have two versions of the MP5 in the game. Won't the 203 version make the standard MP5 kind of redundant in the HUD?
