Paranoia
Paranoia is a three mission campaign created by Eclipse. This is the original Paranoia campaign with a fixed download link, included AIN files and removed unused particles and particle_manifest.txt. Fully compatible with the original VPK, what means that you can connect to each other or to dedicated servers with no problems.
Your team has been sent to investigate a distant IAF outpost. All communication between IAF command and the base has ceased some time ago. You have to find out what happened at this base.
