Getting the medium and hard badges: Step 1. Use your points untill you have full base health. Use your other points to have an even number of points on searching for weapons and searching for survivors. Step 2. During each wave try to get as many headshots as you possibly can using whatever gun you have. Step 3. When you unlock the hunting gun, equip it and the chainsaw. Step 4. During a wave use the chainsaw until its bullets are about 70 and then while still holding the mouse button down, press the space bar rapidly a few times and then stop holding down the mouse. Switch over to your hunting rifle and now your hunting rifle has 99 bullets! Step 5. Use the hunting rifle to get as many headshots as possible thoughout all the waves until you get rescued.

Here's some ideas I've created, seen somewhere else, and have heard people talking about. Single/ Multiplayer campain (missions) against computer players, missions like saving the VIP or something and the humans, robots, and mutants could all be at war and you can choose different missions with different races. Missions would also reward you with money and maybe guns. More maps. Bigger maps. More skins. Cheaper guns. Sudden Death, Death Match. It would be like you would have extra health and when you die, you don't respawn and there would be like 10 or more players in a match. You would get an amount of money depending on what place you came in. So if you were the last one standing, you would be in first place. There would be a lot of health packs so you wouldn't lose too easily. If you think these ideas are cool, + up so the creator might see this and add some of these to the game! :)
LOL The Call of Duty Black Ops Ressurection Ad messes up the game because the ad was on my browser but then i refreshed the page and there was a different ad instead of the Black Ops one and the game worked! And the game didn't work before. :D
