This game could been so much better, If the gameplay was slightly more strategic, and there was more minions. It's an "okay" game, but still it could been better. I enjoyed the game, yes, but It's not revolutionary.
Army of Darkness Defense is surprisingly addictive in its implementation of Tower Defense mechanics in the universe of the Evil Dead 3 movie. Complete with cult lines and humour, it has one other unstoppable force for him as well : it's completely free.
This comes back to my initial concern about the 'Buy' feature. It's not an issue if it doesn't affect game balance but when it does then there is cause for concern. Other than this gripe, it's a great game.
