CarThief has created some more GTA2 scripts and maps. Yakuza VS Loonies Battle includes briefcase battle (capture the flag), team battle and deathmatch mode.
The Briefcase Battle mode
In this mode you must get to the enemy team base, climb the stairs, steal their briefcase, carry it to your own base and place it on the briefcase spot. If you get killed or busted then you lose the briefcase. You can also transfer the briefcase to another team member (if any) by punching them but it may take a few tries.
