Pupa Battle

This is your first battle with an AI boss, and it's a familiar battle style you'll soon be used to. The AI's have a visually noticeable weak point: the red and grey cylinder core. You'll want to arm up with a RPG-2 and Supply Markers. Aim at the core and let loose with your rockets; when you run out of ammo call in a supply drop to restore your supply.

Some of the Pupa's attacks to watch out for are a charge that can be avoided by laying down, machine gun fire that can be dodged by moving, and volts of electricity that have a limited range.

Once the Pupa takes enough damage, you'll need to land a few more shots directly to its core. Failing to finish it in time will cause the boss to restore 3/8ths of its health. When the enemy is defeated, use the action button to enter inside. Here, you'll have around one minute to collect the Pupa's circuit boards, which will come in handy later in the game.
