Verdict: Strong right away in 5-1; once maxed, the free Broken Butterfly outdamages it.
Higher base power and accuracy than an unupgraded Broken Butterfly, plus a built-in laser sight — solid early buy. It does have an exclusive (5x Critical Rate, unlocks in ch. 9), but several bosses negate critical hits and players report disappointing results after fully investing. Once maxed, Broken Butterfly deals more damage per shot. Keep the Butterfly if it's already invested; Killer7 is reasonable if you want power now and the Butterfly is still base level.
