If you missed the Steam Sale for FTL, then now you can get it now. It's bought via humble bundle widget so you wil get FTL steam key & FTL DRM-Free Version & FTL Soundtrack.
A great game, bought it on Steam last week, what it has done to me, I've now spent hours into this game, played it in all my free time done to the last second and pushing my Steam Games backlog even more, it's rogue-like so if your ship gets destroyed you start again from scratch.
You get to manage the whole crew of your ship, deciding which system they be in control of ( weapons, shields etc. ) and upgrading the weapons and systems as you go around the galaxy. Random events await in every system you'll explore like pirate attacks.
Overall a great game.
TD:LR Version: An awesome game which will make you spend alot of time on it, like a space version of Binding of Issac.
