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.

Multiplayer game modes
Influenced by Quake III Arena and Unreal Tournament, Skulltag's multiplayer mode includes game modes including Deathmatch, Cooperative, Instagib, and Last Man Standing. There are also several Teamplay modes, such as Capture the Flag, One Flag Capture the Flag, Team Deathmatch, Team Last Man Standing, Team Instagib, and so on. In the nameship game mode, Skulltag, Players capture the enemy's Skull and take it to a central score pillar where they get points. It is similar to Capture the Flag but more fluid, as the player do not need both Skulls to score.

Bots
Redone in version 0.96, Skulltag includes Deathmatch bot players that can be used in online servers or offline skirmishes. They do not perform well in other game modes, however. Bots have personalities and chat phrases based on their status (winning, hurt, killed, and so forth).

Features

 * Supports most ZDoom features (deep water, skyboxes, transparent walls).
 * Client/server multiplayer architecture.
 * Customizable, dynamic bots.
 * Extra weapons, items, and monsters.
 * Medals to award achievements during multiplayer mode.
 * New multiplayer modes, including Capture the Flag, Last Man Standing, One flag CTF, Skulltag, Team Deathmatch, Terminator and Instagib.
 * DECORATE support for custom monsters.

New weapons

 * 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.

The full set of Doom weapons are also available. All weapons may be placed in maps, summoned via the console, or given to players at the start of a Last Man Standing round. The weapons bunk with their respective Doom equivalents (i.e. the Railgun is in the same slot as the Plasma gun, and the Grenade Launcher is with the Rocket launcher). As a side note, this also shows that those weapons share the same form of ammunition used by their counterparts.
