I suggest 2 possible ways of implementing this:

• You can start a run by loading any save, as long as no story missions have been completed on that save

• You must start a run by loading a save that has achieved 13.37% without story missions and without major glitches.

Edit: No cheats of course on either way

SA Cheat% should be split into two categories - one for War Drum Studios versions, and one for all other versions.

War Drum Studios' versions of the game include multiple new, helpful cheats, including:

• A TRUE invincibility cheat, including vehicle protection

• Weapon Set 4, which includes a minigun

• A cheat that allows you to instantly complete the mission you're on

I would rather suggest banning War Drum Studios versions entirely, but there's already a run using these cheats on the SA Cheat% leaderboard.
