Skulltag

Skulltag is a source port by Brad "Carnevil" Carney, based on ZDoom with network code derived from Quake 2. Its gameplay has been described essentially as a hybrid of Quake 3: Arena and Doom.

Weapons
Skulltag supports several extra weapons that can be added to Skulltag maps:


 * Minigun: Even faster than the chaingun, but has a cooldown pause when the trigger is released, and no first-shot accuracy.
 * Grenade launcher: Fires bouncy, explosive grenades that not only damage enemies on explosion but on impact as well.
 * Railgun: Fires hitscan slugs that can pierce multiple enemies.
 * BFG 10000: Unleashes rapid-fire, hitscan bolts with splash damage which can affect a large area. Based upon Quake 3: Arena's BFG10K weapon.
