A Minecraft look, but an entirely different feel (pictures)
Block Fortress brings three gaming genres together. It looks almost exactly like Minecraft, but the gameplay dabbles in both tower defense and the first-person shooter genres.
You get a ton of different wall types, including many that have the same armor rating so you can give your fortress the look you want. Sturdier wall types like metal walls are farther to the right in the list.
During the game, it will turn from day to night, but that doesn't stop the Goblocks from coming. You'll need to purchase lights and make sure they're powered up so your turrets can see the approaching enemies.
