FPS kit free

Is there any fps kit that has crouch, scope, shoot, enemies pistol, machine gun and sniper rifle. Thanks in advance.

I believe there’s one the tornado twins made. Check their YouTube for the link to their site. Or just look it up in asset store. should be under extensions if memory serves
EDITUnity Asset Store - The Best Assets for Game Making
Here looked it up for you

I already have this but don’t know how t use it I did look on their tuts but I do not know how to change the enemy because if add different enemies in different places they all go to the same place back again
