Kill 30 enemies with the double-barreled shotgun.
Kill 30 enemies with the double-barreled shotgun, cumulative. The double-barrel is one of your earliest weapons and hits hard up close - keep it handy for tunnel mutants and close human fights and the 30 comes naturally. Farm a mutant tunnel if you're short at the end.
