The Kraken [Long Leg (ロングレッグ, Rongu Reggu) in the Japanese version] is a colossal boss robot that appears in Stage 1 and Stage 2 of Razing Storm, one in stage 1 and one in stage 2 of the story mode. One of its kind is first seen in the prologue, with this same one shooting down the player's helicopter. Then it appeared in the hallways using its robotic tentacles releasing two raptors. In the story mode, one appears in stage 1 but cannot be damaged by the player. Another appears in stage 2 which guns down Mark when he got exposed by its searchlights. Subsequently, the same one ambushes the player just before they reach the tower, forcing them to destroy it.
It has four robotic tentacles each equipped with an anti tank cannon, and a long robotic body equipped with numerous weapons, including rocket launchers, laser turrets, laser irradiator "segments" (most of them fire pulse lasers while the top most segment fires a sweeping laser), and an even more powerful main laser cannon. The main laser cannon appears after the Kraken has taken sufficient damage and does so by extending the cannon barrel. While a powerful weapon, it requires time to charge for an attack.
It's weakpoint is the joint on one of its leg, which can be shot by a rocket or missile to immobolize for a while. However, to effectively destroy it, the main laser cannon must be destroyed.
