Game Pick: The Sandbox Evolution
Leo Laporte's app cap on iOS Today 302 is The Sandbox Evolution. This lets you play god by crafting and destroying worlds. It has an 8bit style, uses advanced physics, and has over 170 elements and controllable heroes. This makes it possible to create your own levels and play through them.
You can build a unique world and can manipulate mud, water, sand, fire, metal, electricity, acid, lava, and more. In addition to the people you can unlock, there are also dogs, wolves, bears, cows, deer and sabertooth tigers. You can spread foliage and plant a variety of trees. There's even technology to introduce like batteries, bulbs, heaters, LEDs, sensors, and more. Then you can destroy it all with C4, meteorites, nitro, TNT, or even a nuke.
The Sandbox Evolution is a free game to download, but there are in-app purchases to unlock elements in the game faster.
