If you've ever played one of the Call Of Duty Zombie games you're bound to remember those turrets. I particularly remember them from Black Ops 1, where you'd go up to them pay a certain amount of money, and it sprays away at the zombies. We'll imagine that in Ol'West. Maybe you could pay a certain amount for a turret, then use it as a one time thing, for a certain amount of time.

As I was leading the gang I'm in, I noticed a lot of people AFKing in bases instead of actually helping the gang, so they could rack up gang points. Particularly common in the Mohawk base right under the waterfall. My suggestion would be to set up a system that detects movement, and adds gang points based on your activity, and if they aren't active, no gang points.

Pretty self explanatory, you pay a lot of gang points for it, and as you shoot it at your teammates it gradually heals them, maybe it could shoot a ray so you know where it's going, and so it's not so overpowered it could have a cool down. I got this image to show you an example from a game. As you can see, a green ray is shooting out of a light, one which heals the player.

Once again pretty self-explanatory, you throw the bombs, and a circle appears once it guys the ground, and instantly any teammate in that circle will be healed to a certain extent.

For a certain amount at the gang point shop maybe you could buy a wall to place down, and it has a certain amount of health which players have to destroy, but in the meantime you can do things such as heal or get your safe up, but there could be a cool down period so it's not too overpowered.

You can get planks to barricade the doors, players either have to destroy it with a melee as a second barrier, or wait a certain amount of time.
