Gameplay Specifics:
-------------------
viavga_dm1 is the first of several Doom 3 DM maps I have planned and following versions will explore other sfx available in the new engine and will likely be influenced based on feedback from this map.
Features: Exploding barrels (no respawn, immediate explode) and exploding gas tanks (no respawn, 1 second explode), some shootable lights (hanging fluro tubes) deathtrap squisher tunnel (near BFG) that can be activated by 2 nearby switches. Various scattered weapons (all multiplayer weapons featured) and ammo, 1 megahealth powerup and 1 invisibility powerup. Beware the lava :D
