Engineer

The Engineer is one of the playable characters in Risk of Rain 2.

How to Unlock
The Engineer is unlocked upon completing the challenge "Engineering Perfection" (Complete 30 stages.)

Tips

 * Getting several Bustling Fungus and stacking Turrets on top of each other is a great way to cheese certain bosses. This isn't as effective on the Magma Worm, but the turrets auto-aim may make this boss easier to fight none the less.
 * A single Hardlight Afterburner can allow for 100% uptime of Bubble Shield.
 * Stacking Bandolier can lead to a constant up time of your Bubble Shield, allowing for good cover from Wisps and Titans/Colossus as the time ticks on.
 * Pressure Mines can be stuck onto the outside surface of the bubble shield and other players.
 * Leeching Seed is a high priority item, as it heals your Turrets as they deal damage.
 * You may sprint while Bouncing Grenades is charging up. Deploying Bubble Shield will not stop sprinting.
