Twisted Metal 2, Black, or Twisted Metal for PS3.
The stages are the best in these three games, but the newest one has far better stages than the rest. Twisted Metal for PS3 gives you the full stages which are best for 16 person matches, but the game gives you smaller versions of the same stages with relocated pick ups if you're using a fewer amount of people or you want a more confined match. All of the games have multiple shortcuts to different areas of the stages.
Twisted Metal 2 and Black have better designed vehicles in my opinion. Twisted Metal for PS3 the specials have been reworked and there are a lot of specials that feel too similar, especially considering vehicles like Kamikaze and Crimson Fury or Death Warrant and Road Kill are mostly the same, with Crimson Fury and Road Kill being the better versions of each.
The newest Twisted Metal set the ice, shield, mine, and fire behind to your left digital pad, you can do turbo in reverse, each vehicle has two specials, and in the case of Road Kill there's three because of the mines. They've added weapons like the shotgun which does more powerful close range and max damage 60 if right on them at the front windshield. The sniper rifle which will target the body of the car, tire, gas tank, and finally a head shot for an instant kill so long as if you can maintain view of the vehicle during that time, but have to start all over if loses aim then regains sight of them.
The online on Twisted Metal works now. Only took them six months, but it's also not ideal. Sometimes in death match, you might come across people who team up together, and if it's not the netcode, there's also some people I feel use lag switches(and as small as the community is now, that's a disappointment.) The only thing you can guarantee is that when you get online, you are more than likely not going to come in first place, more than likely not going to even be close to that. The people who still play on there, the ones that are good, are actually very very good. This isn't just based on "these guys are getting first here and there," this is based on a lot of really good techniques that these players follow and they get first each and every match, and not because they're cheating.
