The idea of the game mode is based on the Western Film - 3:10 to Yuma, if you have'nt seen it yet, I highly recommend watching it.
Anyway, the whole idea of the game is that there there are two teams, The lawmen, and the Outlaws, basically, the Lawmen have captured an Outlaw and have too escort the Outlaw too the trainstation somewhere (Its in the film) Meanwhile, the fellow Outlaws are trying too stop the lawmen from doing so, and getting there Outlaw Leader back alive.
So, The Lawmen Will have the outlaw allready (Unless they wan't too try and capture him) and will start at a location somewhere far away from the trainstation.
Whilst the Outlaws will start somewhere imbetween the Lawmen and the trainstation (too make it easier, Or start behind them like in the film). However, the lawmen have too make it easier for the outlaws so have too stop of a 2 - 3 towns and stay there for 2 - 3 minutes real time, (makes it easier for the Outlaws)
I have'nt decided whether or not the captured outlaw is aloud to shoot back at his fellow outlaws too make it more fun for him or whether or not he will just have too sit out?
Anyway, If the Lawmen manage too stay alive (If you die, you're out of the game and have too sit out) and manage to get the Outlaw too the trainstation, they then are aloud to Kill the Outlaw causing the game too end, and them too win. However, if the Outlaws manage too kill ALL of the Lawmen and get back there fellow leader alive, then the game ends causing them too win. Simple.
Post what you think, and/or any other ideas which can be added too the mode.
Also, i've written this quite fast, so if some areas don't make sense or if i've missed something out, tell me.
