The badge is much easier to get by switching the difficulty to easy. I bought the assault riffle and then the minigun. You should have a high enough score by level 18, but I got to level 26 before I got bored and suicided.
Dead on Time should be an impossible badge. The +2 seconds from hitting zombies just isn't enough to make up for the time between each one. Combos could mitigate this, but they disappear too quickly. Along with the insane penalty from hitting a civilian, hitting 10K is impossible. I average about 3K with a fully upgraded car. No matter how much I try, I can't even get close to 10K.
The windshield wipers are a nice touch. 5/5, but you can still make some improvements like more upgrades, a pause button, and a tutorial. Maybe some way to shoot your gun at targets that aren't just on your windshield.
I love the visuals, the new TD elements, and the targeting AI seems solid thus far. The story (though simple) makes the game that much deeper too. Great game overall! 5/5
The energy mechanic has to be the stupidest feature I've ever seen in a game. kingk, do you really want to force people to not play your game?? That's what it does! Now I'm going to go play something else until it recharges. I might come back to this game later..or not. 3/5
