Tech Hunter combines shotgun combat with explosive ordnance and tactical positioning abilities. This character starts with limitations but scales into a formidable force through upgrades and artifact synergies.

Tech Hunter's unique mechanics include teleportation anchors and orbital strikes, requiring players to think strategically about positioning and resource management throughout encounters.
Tech Hunter's Unlock Requirement
Go to the Aurora planet twice on each run. If you want to keep running beyond stage 12, you may do this by talking to the Quorium.
Tech Hunter Abilities
You'll get off to an awkward start with Tech Hunter, desperately trying to snipe down enemies with your shotgun while staying at close enough range so your pellets overlap on them.
This is largely fixed long-term because upgrading the shotgun gives additional pellets, makes pellets inflict bleed, and allows them to pierce enemies, turning your attack into pseudo-AOE with cleave damage.
If you prefer building into grenades, you can spawn extra grenades by killing enemies with the Vacuum, but this requires three upgrade levels. In the meantime, you need to kite enemies in a circle so they don't move out of your grenade's explosion radius.

The movement skill, Trace, is make-or-break for this character. You'll either love the ability to drop a copy of yourself at an objective, run halfway across the map, fight enemies, then instantly teleport back to complete the objective, or you'll hate forgetting to drop it during siren fights and teleporting back into AOE attacks.
Onslaught, the fourth ability, works out of the box as a fire-and-forget orbital laser. If you want to orbital strike anything out of existence, max its upgrades first. Because it can drop fire puddles like the grenades, there's elemental damage to kite enemies afterward.
Tech Hunter's passive, Hunter's Luck, gives you a chance to drop random modifiers (white tier artifacts). Because you can get extra power, you start weaker but scale incredibly well by the endgame.

You should target sirens directly rather than ads when using Onslaught, as some enemies are highly mobile and likely to move away from your intended target.
You'll have the most success maxing the first and fourth abilities, though the infinite grenade bouncing can be effective as well.
