Mars! The Red Planet! That Old Space-Apple. Rusty Roundface, we call him. Today you can explore his craggy pores, as Arma creator Bohemia's Mars rover sim Take On Mars is now on sale with early access. NASA's Curiosity rover cost over $2.5 billion, so at $12.99 the game is probably your best chance to tickle Rusty's nose.

Take On Mars puts you in charge of Mars landers rovers to poke around, conduct experiments, and try not to destroy hugely expensive machinery. Along with a campaign, where you need to develop new rovers and instruments as you go, it has individual scenarios and an editor.

It's available direct from Bohemia, who simply give a Steam key, or on Steam itself.
