Vector Conflict: The Siege

[{Remnant} CT-5108]

There's this retro-type game called Vector Conflict: The Siege (which I almost always spell wrong) and basically you're in command of... I'll copy and paste the description:

"Description: Vector Conflict is anintense 3D shooter set in a bleak, post-apocalyptic retro world. You are in control of the defensive systems for the vast SOTER underground bunker. You are the last line of defense for the survivors taking refuge below – protect them at all costs."

It's really cool and free to play online any site (singleplayer game) play it!
