Easy way to get the medium badge if you hate this game as well. All you do is keep pumping your karma into one or two ninjas. When you go to select a group to fight, scroll down to the bottom. There will be some groups that are created by the game. Select the group with the largest army as your group should kill most of them in one shot and not take much damage. To make things go quickly, as soon as the fight starts, click skip up on the top-middle of the screen. The money you make from this will pay for your hospital fees after every fight and you should start getting a large amount of excess money. When you fight a group for the 5th time, they will be unselectable for about 10 minutes. Just choose the next army on the list with the biggest army or go back a level by clicking weaker on the bottom left of the screen where you choose where you are going to fight. I did this and I got my medium badge within about an hour of playing.
If you want to check your achievements, play the game on Newgrounds. They sponsored this game, so the in-game achievements were implemented with that site in mind.
Found a glitch that breaks the game. If you put a spike trap at the start of a map, the monsters will get stuck on them for the rest of the map. You can even walk through them and take no damage, but your turrets will still fire on them.
This is the best game I have played on Kong in about a year or two. I went into it thinking it was some game where you just tried to kill as many zombies as you could, but I was very pleasantly surprised. As soon as I saw the name EvilDog on it, I knew that it would be fun to play and have amazing music. It has original game-play, an interesting story, and a very smooth learning curve. The only complaints I have would be that it feels as though some of the upgrades don't really do anything long term. The windshield upgrades are made unnecessary with the body armor upgrade if you learn how to avoid gunfire, perception was more or less an annoyance until the final upgrade, and when you have a maxed out engine, the horn doesn't really have time to change anything. But those could merely be because of how I played. This game is going to be one of the few games that I actually link people to on kong. Congrats on making such an amazing game!
This game actually taught me a lot about fire safety. In fact, I think I'm going to move my boxes of bombs away from my fireworks right now to avoid any kinds of fire hazards.
