Shiver me timbers and walk the plank, me hearties, because Bundle Stars are running a seriously cheap Pixel Piracy deal.
This sidescrolling piracy sim allows you to make your own ships and plunder to your heart's content, but better yet, it's also ten times less expensive than the Steam RRP if you buy from Bundle Stars. 69p versus £6.99. That's a whole lot of pieces of eight, yarr, also other pirate cliches.
Note that Pixel Piracy has been in plenty of bundles recently though. You may already own it!
UPDATE: It's even cheaper at Gameoxy! Click to buy Pixel Pirates for £0.49. Thanks for the reminder, Buzz!
