If you hate dying, and just want the emblem, use the save and quit feature once you get to a checkpoint. If you die, just back out to the home screen and restart your disk, and resume playing. I got through shutdown (cause skips) in one go, but I had to 'save and rage-quit' on reclaimer because the major skips in that one require a good handle on the jet-pack.
See and that's the thing that got me, in Reach you would get weekly (or daily? I can't remember) challenges to complete a mission of the campaign on LASO difficulty, but the Blind skull was never included because it's too much of a pain in the ass. I did the LASO in H4 without Blind on and it didn't count >.<' ****.
At least some of the LASO challenges in Reach included the blind skull. I distinctly remember taping a reticle to my tv in order to try and help me get through a specific part for a weekly challenge.
Yeah put some tape that isnt clear but still allows you to see through it. I used paper tape. I think its called that. And if you want to check your weapon just press the back button. It tells you what weapon and armor ability youre using
