I like the sound of 'The Fugitives', they could make it a class CopsVRobbers mode.
Equal teams of cops and robbers (Or maybe more cops, more like real life that way).
Cops start at a police station (duh!). On the roof is a hunter, maybe a VCPD also. On the ground, many Police cars, a couple of cheetahs, white Freeways and S.W.A.T vans.
Robbers start near the sailor spawn docks, with a large black truck, some PCJs, maybe a black maverick. Just some nice cars and a large transport one.
Robbers must get to bank, find the 'money' and my ideas are either:
a) Robber holding the money must survive for a set time
b) Robber with money must get to 'hideout'.
