Absolutely trash. I downloaded it and completed it in less than 3 hours. And as for the 'destructible vehicles', they snapped like twigs. I couldn't get through a level without them breaking half way through. And yes, I did use armour, but It's completely useless. If you're going to make a game free, don't spend a day making it and be lazy enough to just spend 5 minutes reskinning the same models. In short, great game!
