Orion is a promising online multiplayer total conversion utilising Valve Software’s Orange Box engine.  Featuring fast-paced tactical gameplay on futuristic battlefields, Orion brings back the glory days of old school reflex type gameplay.  Featuring all the classic online game modes like CTF, Deathmatch and Team Deathmatch, Orion will also feature a special unique game mode called vital.

We will be going old school with the Deathmatch in Orion. There will be no player classes and everyone starts with a default weapon (can be modified by server hosts, however its the pistol). Everyone has a jetpack by default and weapons are scattered around the map in a retro-deathmatch style.

The Closed Beta starts Friday, December 4th, 2009 and is available to all Fileplanet members.
