Doing a blockout and gameplay stuff first is wierd. Based off of this ODST concept art. Definitely a BTB map, but I'm not certain what vehicles to put on it. Happy to take advice and criticism.
Are you going to include that street surrounding the concept art? Would be kind of Rat's Nestish so I say Warthogs and a Ghosty. Maybe a Mantis to be trolly.
The street (and the small building on the bottom right) are included. Warthogs will be on it for sure, and maybe a wasp, but I'm not sure how to do ghosts. I was thinking a neutral ghost ultra as a power vehicle.
I personally say forget the vehicles. Make it infantry only. Especially because the map isn't specifically designed around it.
BTB maps without vehicles always weird me out, but i have had difficulties adding structures to the outer layer. I'll try it out with no vehicles.
consider, that in customs, often times you will have a not-so-full room and the few ppl go grab the tanks and shhtuff, and then the others leave because it is unfair to be spawn killed repeatedly by a banshee, for instance. I wish vehicles would only spawn if player count > specified number. hmmm... maybe there's a scripting project for someone (me)?
