This TDM build is good.
But the gameplay is really crippled. You get 1/2 grenades and 1/2 RPG for each player (6 explosives WOO, + 1 Conc). No objective except elimination makes the entire battle in one small area of the giant oil rig due to groups, losers running for their life, and while terrorists can easily spread out, "Oil Rig" team starts in a small room deep inside the oil rig with no real advantage. Also, what do you think about "11 ammo shotguns" with Pump Shotgun and Scattergun to switch right into?
RP-TDM also is bad, having to need leader orders to start fighting.
But really, this has a big potential to be a great TDM or DM.
Just place the objective more carefully and fix up the small stuff and this can easily be awesome.
I played this during the weekend, so also forgive me if you already made a few of these changes.
