Instructions
Play through the game until you pick up the Stasis module. The module is located in the maintenance tunnels on the way to the tram.
Use the right analog stick to aim at the enemy or object you want to slow down. Hold down "L1" to ready the Stasis module.
Press the "Square" button to fire a Stasis beam. Each beam you fire reduces your Stasis meter slightly. When the meter is empty, you cannot use Stasis until it is refilled.
Refill Stasis by using portable refill packs, found in containers or when you kill enemies. Stasis refill stations are also available in some areas.
