I will inform all the bugs found here.I found out that the hitman bike, cars are not faction protected. Any one can drive them. The heli works fine.
The hq would be nicer else where. got a few ideas ill show you in game if your intrested.
Hitmans should get an knife and an eagle when they spawn. And an possible weapon shop at theyr spawn to serve as the interior as the hq also, That way they can support theyr members with free/cheap weapons.
And civils, dont metagame the hitmen, irl you dont know who is an contract killer and who is not, so you wont know in game either. Gonna kick ya ass if you metagame them.
