Mmm... You could try to switch the places of flags in almost any CTF map. It would be similar to bombing run imo. You could also turn off some weapons like spas or m79.
And separate maps would probably enhance the effect. For example
something of this kindIn this example you would need to fall from the spawnpoint and grab the enemy flag, then run along the bottom, and throw the flag up, so that your teammate at the other flag (waiting at the enemy base) would catch it and score.
Or a teammate could boost you with a law from below (if spas, m79 and mini are banned). Then you would cap tourself.
That thing would be insane imo
. It would require a good team, and actual capping would be quite hard
Again that's just a product of my twisted imagination. Maybe someone already came up with this idea, idk. But it's quite interesting, someone prolly should check it out...
