Chrysalis Battle

Being another AI, the Chrysalis fights much in the same way as the Pupa. Some of the items you'll want for this battle include the FIM-43 and some Chaff Grenades. The FIM-43 can lock on to the boss, allowing you to score deadly shots without much fuss. Chaff Grenades are also great, as they will stun the Chrysalis, preventing attacks and giving you a clean shot from other weapons.

The AI has a powerful railgun that can do a lot of damage, a standard machinegun, and can even attempt to kidnap you with a grappling hook. If this happens, quickly rock the thumbstick to break free.

After enough damage, the Chrysalis will fall, allowing you to enter the core and nab more circuits. A note about this battle: You'll need to complete this mission with a S rank, otherwise you'll be unable to play certain secret missions later in the game.
