There's one thing you can do to get more health. You need to find a "player".ini with more hps than the one you use in MP. Just switch the names of those two and you'll have more HP + you can also skin hack (that's the funniest cheat I ever tried). It's possible it works like 1.30 or the old demos.
But all cheats that are made now will be fixed quickly later, they are only checking the cheats out first before they fix them.
