Ive had tremendous luck with CoSMOS, foudn the usual rez, goons and scrap very easily, but most notebly finding the values for total xp, and current level. Im not sure if the enemies scale to you, so i froze my current level at 50, and set my total xp to enough for 51, and you jsut keep levling up, getting an insane number of bonuses/perks.
I used CoSMOSs speedhack to crank up the gamespeed, and used a macro to rapid click and left it for 5 mins, when i came back, i had over 250k hp, about 50k shields, ungoddly amoutns of armor, capicter, regen booster power, everything. And while it would have made me lvl 1000 or so the amoutn of tiems it lvled me, im still 50.
