We all know our group members -- start a gang war and less in 10 seconds they all dead.
Rather than focus on shooting enemies, you just spent the whole war wondering why Sweet bothers himself for the whole storyline keeping the gang alive.
OVERVIEW
- Simply recruit your gang members and their stat will boosted immediately. (a green marker will show up above the member)
- Share your current weapon by aiming at them and press Y.*
- Release a group member by aiming at them and press N.*
- If all tags sprayed, the gang members stats boosted even more. (More health, Hitman weapon skill, Immune to fire and crash)
ATTACK-READY MODE
- Command your group in attack-ready mode by pressing J*, your group will locate enemies immediately.
- In this mode, your group will attack same target, which is marked*.
- Aim at other enemy and press TAB* to change your group's target.
- Press G* to cancel attack-ready mode and regroup immediately.
*Adjustable in config
BUG
- Sometimes when you recruit a gang the member wont get improvement effect.
- If the member didn't get improvement effect, simply release him and recruit him again.
