A half Life1 Opposing Force mod. You're Corporal Shepard. A Soldier which arrives at Black Mesa in an alternate reality. Another Experiment went wrong and your mission: To find out what happened in Black Mesa and rescue the trapped personnel in it.
Just a little show of on what I'm currently working. Black Mesa personnel will finally get more than their Jeeps.
It's still WIP though I'll try to add more details to the chopper.
Also the rotor is nothing less than a texture sequence as real rotors wont work in combination with a move script. Very sad but that's the only solution.
