Chaosphere is a short side story mission in Episode 3.
Mission Summary[]
You lost contact with the AMC when you got sucked into the mysterious artifact known as the Chaosphere. Find a way out!
Note: This is an optional mission, and is not required for completing the episode.
Gameplay[]

Watch your step. Hop around, kill the PE Troopers. When you get to the weapon on the southwest, a forcefield for the teleporter will disappear. Use that teleporter. From here, you can choose to go left or right as the front is locked with two forcefields. On the left, fight Le Sang's minions, then head to the end with a megasphere to unlock the forcefield. You can also cross the bridge here to find slot 7 weapon. On the right, head up the castle, fight Berserkers and Ogres and hit the switch to disable another forcefield. Note: the corner room with the ladder takes you to a different floor of the castle instead of the roof. When both forcefields are deactivated, gather the ammo, then go through the main teleporter and face the Scarab Demon.
By beating the level, you take the Chaosphere back to the base, but in order to use it and unlock extra levels, you need to have the Paranormal Research Room researched.
Weapons & Artifacts[]
- MSC 12 Shotgun (Weapon, Mikko): located on the second floor of the castle.

Trivia[]
