I've finished this level twice with picking up the key yet at the end it won't give it to me. Finished Once with dying and once without. When i got the clear box gem i was too keen and didn't pick up the key. I've seen some people saying they can only be picked up together? Possible glitch here?Posted by UK GOLYMONSTER on 13 Jul 18 at 21:47 @UK GOLYMONSTER, repeat the level and get the key at the cortex bonus portion of sunset vista and finish the level MISSING a few boxes and the achievement should unlock along with the key.Posted by El Luigi on 13 Aug 18 at 05:24 I just got the clear gem even though I died a few time. I got the key achievement popped at the end.Posted by beets101 on 22 Feb 19 at 15:25 Leave a comment
