wasd or arrow keys to move. Mouse to aim. 1 - 6 keys to switch weapons. after defeating all the enemies on a wave you will get a chest press "c" key to open it. The next wave won't start until you collect a item from the chest. You can't get rid of the weapon in the first slot of your inventory, and it is the only one that has infinite amo. Don't click the amo item in the chest it isn't complete and it won't work. reload your weapons with "r" key. If your wondering how you get more amo you can only get it by getting a weapon that uses the same amo as a gun you already have. The different rarity's increase the damage that rarity times the damage. If you ask me why the med packs are not working, I know already they aren't working and I will fix it in the full game and not the Demo. Also have fun. If you have any question message me in the comments.
