The Sandbox Evolution [Free] is a great tool for creative types, and it's been updating constantly ever since it appeared on the App Store. A few weeks back, it got a Pac-Man update, which?unsurprisingly?allows players to create and play their own Pac-Man mazes. The upcoming update is going into a different direction by bringing Zombies to the game. As the developers described in our forums, the new update is all about Arnold and his mission to protect survivors, stay alive, and, of course, kill as many zombies as possible. The update will bring 5 new zombie-themed elements (Zombie, Stalker Zombie, Bloated Zombie, Zombie Virus, and Antidote Particle), 4 new weapons for Arnold, and much, much more.
As you can see from the screenshot above and the gifs in the forums, the sprites are really cool and, as a forum member pointed out, look like Metal Slug. The update will go live March 15th on both iOS and Android.
