I may have forgotten to set one of these to "night." I'll never know, because I neither play deathmatches nor edit my work (though I do intend to edit War Never Changes II... someday).
Los Santos Warlords I
You've been selected to compete in the Los Santos edition of Warlords, a brutal reality show operated by the warlord himself, Massacre. Find a weapon and fight for your life.

Straight melee, but molotovs, because I can't fucking resist them.
Los Santos Warlords II
You've survived the first stage, proving yourself superior to those who did not. More bloodshed shall be your reward.

Added grenades and sawed-off shotguns to this one. Also, each side of the map (in case of team deathmatch) has a combat MG and a grenade launcher. The grenade launcher isn't that useful given all the sheds and train cars on this map, so I didn't think it would be troublesome. Don't play it as a TDM, though. It'll only lead to grenade launcher-camping and a sense of safety.
Los Santos Warlords III
Again, the weak are culled. Again, you prove your strength. Again, you will be rewarded. Revel in the slaughter. Let the symphony of gunfire fuel you.

This one is pretty much a straight shootout, plus the fun thrown weapons. Two spawns each for rocket launcher and grenade launcher. Again, the environment makes them difficult to use correctly, and you need to be somewhat in the open just to get to them. There's also a sniper nest that has no good cover. That's what you get for being a bitch and avoiding the fight.
