That's right. After doing some research, I have concluded that turning on the Tilt skull actually makes the campaign easier. I have completed the Reach campaign solo, legendary and I have completed two of the Mythic (LASO) weekly challenges SOLO (films in fileshare). It seemed to me that Mythic difficulty was more forgiving than Legendary. Sure your enemies are a little more super charged, but it seemed that it was harder to die with all skulls on. At first I didn't suspect the Tilt skull because the description (in Halo 3) says "All enemy weaknesses and resistances double." So I didn't believe this applied to Spartans. But once I realized that something was different on Mythic I did some research. First, on Legendary difficulty with NO skulls on, it takes 13 individual plasma shots to kill a Spartan. Exhibit A: [url=http://seventhcolumn.bungie.net/Stats/Reach/FileDetails.aspx?fid=14807431&player=dukemeiser]13 shots legendary[/url] Second, on Mythic difficulty (Legendary all skulls ON), it takes 19 individual plasma shots to kill a Spartan. Exhibit B: [url=http://seventhcolumn.bungie.net/Stats/Reach/FileDetails.aspx?fid=14807406&player=dukemeiser]19 shots LASO[/url] Third, on Mythic difficulty with Tilt skull OFF, it also takes 13 individual plasma shots to kill a Spartan. Exhibit C: [url=http://seventhcolumn.bungie.net/Stats/Reach/FileDetails.aspx?fid=14807415&player=dukemeiser]LASO Tilt OFF[/url] Lastly, because Spartans become resistant to plasma, it is possible to survive a direct sticky grenade with the Tilt skull on. Exhibit D: [url=http://seventhcolumn.bungie.net/Stats/Reach/FileDetails.aspx?fid=14281621&player=dukemeiser]Stuck in face, did not die[/url] The last film is actually from one of my Mythic attempts on Sword Base. I rendered it because it was impressive. I rendered the first two videos for casual viewers, but there is no way you can count the plasma shots online. I had to watch the film in slow motion in the Theater to count all the shots. I also turned ONLY the Tilt skull on and died in 19 shots so my theory is correct. My conclusion? If you're having trouble completing the campaign on solo legendary, you might try turning the Tilt skull on. What will this mean? It will mean that all of the shots the Covenant fire at you will have less damage. It will take about 50% more shots to kill you than normal. The downside is that popping an Elite's shield with your DMR will be nearly impossible, but you shouldn't be doing it with your DMR anyway! The best way to pop an Elite's shield - Tilt or not is to use plasma weapons. The Tilt skull does not affect headshots. One DMR or pistol shot to any unshielded enemy's head will kill them. Therefore grunts, jackals, skirmishers, and brutes without helmets will all die with one shot to the head. The strange thing is that shields actually take MORE plasma shots to pop with Tilt. Vanilla Legendary it takes 4 plasma shots to pop a Spartan's shields. Mythic it takes 5! Which means 9 unshielded shots for the kill on Legendary and 14 unshielded shots to kill on Mythic. Elites are the same with 7 plasma shots to pop an Elite Officers shields on Legendary and 8 shots with Tilt. An overcharged Plasma Pistol shot will NOT pop an Officers shields with Tilt. One additional shot will pop it, so the n00b combo will be slightly harder. I've always found that peppering their shields works better anyway. So if you still haven't got [i]A Monument To All Your Sins[/i] achievement yet, try the Tilt skull and see if you like it. If you're playing the campaign on Normal, I wouldn't bother. You could probably melee every enemy in the campaign on Normal difficulty without dying. Which sounds like a good challenge...
