The game
Two halves of every day
Mine by day
Break rock and crystal seams for Red, Purple, Amber and Obsidian. Every crystal builds something different.
Build and power
Raise walls, guns and generators around your Base. Most towers run on power, so route it, store it, or feed it by hand.
Hold the night
Waves come out of the cold after dark: 7 kinds of enemy and two colossal bosses, each with an attack you learn to read.
Switch at any time
First person or commander
Press one key to rise out of your character into a top-down commander view. Place towers on the grid, send yourself to mine, and watch the waves come in. Drop back down to carry a gun to where it's needed.
Every gun tower has a weapon you can take off its stand. Carried guns can't be frozen by the bosses.
