Ok.. easy way for the game. Start with The glock and get the extended mags and sight. Full auto and silencer do nothing. And although the glock is a terrible gun (real life and game) it has lots of ammo. Save up for The AK74 then get whatever you want. After that its up to you.
Kind of a Stupid comment but if you want a "Sin City" look to it. put skin tone all the way up and the other 2 down. then put blood on white and then put everything but stage on grey. (#99999 in case you cant find it.) and leave stage pitch black.
Hey.. you can mkae them "hold" object with the motor and rigid joints. just then joint the rest of thier body parts together with elastics so they stay together.. that way they can beat eachother up. i made one sit in a hciar while the other one ripped him apart with a pickaxe
