Obviously for ut99, XVehicles is the way to go but someone made Onslaught vehicles for it too a stretch back and while they're admittedly not as good they do come in a much wider variety of stuff from air ships to hovercraft to ground units...

...which I only know as I found this Face map I've edited quite a bit that had some of them on, but I switched up what was there as a lot of it wasn't ideal for a space environment.
First off, the Team Color situation is tragic...

...most of the vehicles don't have any, and the few that do only have Red & Blue. Despite that glaring flaw, they all do work remarkably well... even if the turrets occasionally fall from where they're placed but keep shooting all the way down!
I haven't seen any instances of someone in a vehicle hanging onto a flag, but I've only tested this sporadically and there's a lot going on.
Speaking of which...

...I have a UTDMW on the map too.
Originally I had 1 for each team but due to the EXCEEDINGLY FUBAR'd issues with the newest UT-patch, which doesn't allow UTDM-monsters on teams to function for some still as yet not understood reason... I opted for one unassigned as that does allow it to function.
So, not as good overall but still fun to mess with.
