There should be a training room, 6 people can join it, all are allies and they're training with a whole bunch of bots. They can add/sub the number of bots and what guns they have and hp/def! Also shooting range idea is cool, but need dumbies, you can active ever idea from here and active if they're moving or not.
Single player missions that gave a certain amount of money the harder the level is, say the easer levels give 50 coins and 50 xp, and so on would be nice.
