Pro tip for survival:Take all the upgrades,and die on every 3 to 4 thousand meters,then switch arms because pressing the "up" button for 10 straight minutes will stop all the blood in your hand...
Found 2 bugs:Ghost Summit does not add critical chance although it says so,and it seems that combined with Claws of Darkness it actually reduces your crit. chance by 20%.Vote this up so dev. can see this.Great game,expecting a sequel!
Nice game.By the way, can you add extra difficulty setting with limited ammo, which, for ex. you need to pick up through the level?It's just not fun when y have that deep pockets (zombies would agree too). ^^
