I wonder if they can do 100% category? (All wapeon max upgrade, all gold bolts, all promotions) .

Yeah sure! Seems interesting! Wanna try out? If you make it, I will sure create this category ;) (and beat your time a posteriori xD)

Would this also include all skill points (except the 5 multiplayer SPs)?

We can do anything! A 100% categorie with everything but the multiplayer SPs and a (let's say) 95% categorie without SP. Just run anything you want in this game and I will be happy as well as you ;)

a great idea, and for the 5 skills points from multiplayer mode, i think we must ban that, because if in the future, somebody say "they can have the easiest skill point from multiplayer and save so many minutes, it's unfair" with QFORCE42 we talked about that and we are okay to try this category
