if you're having trouble with lvl17 challenge, try killing all except two ground gunners, get them together so that they shoot at the same time, then 1) maintain slow motion 2) dash w/ anti bf into their 2 bullets 3) teleport out 4) repeat 2&3 twice. This should mean you evaded 6 bullets, but the first probably went and got nullified by the plastic shield. Also, the game somehow recognizes those plastic shield messups as evades for the "untouchable" medal, but not for the hard achievement. *sarcastic woohoo*
