Those birds in Bastion can eat a dick.
No pattern, no recovery, no nothing.
You mean they can suck a bag of dicks.
They can be safely deleted after you have ran the game at least once, they are never needed after the first time startup. Also if you ever need them back for whatever reason just verify game cache and Steam will redownload them.
Ran the game once huh...Oh oh.
Okay then, I'll just do it when I run out of space (still have a bit) and if I run into a game that needed it I can just hit verify cache, should work. Thanks.
