Surviving Mars' domes, in which your colonists live, are one of my favourite things about the game. They're full of colour and light and really stand out from the dusty backdrop of the Red Planet. In an update on Monday, developer Haemimont Games will add five more dome types of various shapes and sizes, and they look very pretty indeed.

I especially like the design of the barrel dome, which you can see below. It's quite small, but it won't require many resources to build, so it should be handy early in the game. You can say the same for the micro dome, another cheap dome that's triangular in shape.
