Cannons Lasers Rockets is a free space exploring game available on Steam for Linux and Windows with 3D graphics and futuristic space environments. The game was released on February 4, 2014, uses the powerful Unity Engine and takes place in various space environments, with 2D battles and a simple gameplay idea: all you need to win are three weapons, obviously cannons, lasers and yes, you guessed it, rockets.
I was pretty reluctant in trying Steam on Linux ever since it was made available, but what made me install it was that Counter-Strike is now available on Linux via Steam too. I used to play this a lot a few years back and CS for Steam was put out on February 6. So I bought the Counter-Strike Anthology pack during this weekend deal and decided to give it a try.
