ミュータントアーム

• Contrail - If the player has [エイリアンエンジン] , its flame will turn green, igniting enemies with permanent green fire . [エイリアンエンジン] also grants flight while held.
• Neo Tech, Yo - If the player has [サイボーグ レッグ] or [ショック弾] , Mutation's beam turns blue, leaves puddles of electrified water, and its ammo capacity is increased to 800. The player is immune to electricity while Mutation is held.
• Venom Veins - If the player has [モンスターの血液] , [怪しい目薬] , [血ぬられた9mm弾] , [血染めのスカーフ] , or [血のブローチ] , Mutation poisons enemies.
• Mutation is not a proper goop -spraying weapon, unlike the [メガウォーターガン] , the [ポンプガン] , or the [化石ガン] . Unlike those three, Mutation's "stream" loses all momentum and immediately ends when you release the trigger.

• The synergy between the Mutation and [サイボーグ レッグ] / [ショック弾] may be a reference to Tetsuo from the 1982 manga series Akira . Tetsuo similarly possesses a bionic arm, and famously undergoes extreme and disturbing mutations. The synergy's name, "Neo Tech, Yo" also seems to allude to Neotokyo, the setting where the story takes place.
• "Didn't Need Two Anyway" refers to the look of the weapon in-game, which envelops the player's whole arm. This visual effect is also shared with [ロボットアーム] , [ロボットの左手] , [ヒロイン] , [フレイムハンド] and [ロックハンド] .
