Hi there.
I created an unique melee weapon and when the player will equip it, two things should happen:
1. The enemy faction will be set to ally (for example I suppose I can use "Player.SetAlly BLFaction PlayerFaction" command)
2. An unique sound starts to play
Of course when the player will unequip the weapon, the effects will dissapear - the faction will reset and the sound will stop playing.

Please help...
