Blast From The Past: Strange Adventures In Infinite Space
The Strange Adventures In Infinite Space series heavily influenced FTL as the original permadeath space odyssey, providing an entire procedurally generated galaxy to explore, loot, conquer and constantly surprise you in the space of a lunch break. The first two games were utterly superb and I have little doubt that the third will surpass them. The early access Steam build is currently only $1 -- 60p -- so get in on the ground floor.
Alternatively, pay £1.05 to also receive the first two games in the series. Thanks to TehJumpingJawa @ HUKD!
