Here's the game in action:
Thumbs up for a proper login system, plus a 'backup' of your credentials via the Photos app (screenshot), should you log in as a guest. Very nice.
The main game area/mechanic. You set up gunfighters on a 5 x 2 grid, upgrade and re-arm them as needed, and then they auto-fire on approaching zombies. Energy/ammo bars keep you informed as to how things are going. Let any of your fighters die and it's level over and try again.
Plenty of polish in the UI, including this sliding door animation to launch a level.
The main game menu, showing the level sector and other game areas.
The Shop shows in-app-purchases only up to $16 and most are quite small, which is a welcome change for freemium. So, if you do get into Zombie Survival: Addictive Tower Defense then your outlay is only going to be a handful of dollars.
You can grab this in the Store here. One for tower defense/zombie crossover fans, only?
