He can attack solo and function as a fast moving scout class, transform into an Oak and operate as a slow moving explosive class, or ride on top of an Oak as an Acorn Passenger and function as a playable mounted turret.
Acorns work best when they attack in groups. Transform into Oak, and load up with Acorn passengers who'll get increased firepower and survivability.
Deal lots of damage, or use to suppress opponents
|Launch a sticky knockback explosive. Press [left button] to detonate.|
|Transform into an Oak. Joinable by up to 3 additional Acorns.|
|Quickly spin in the direction you're moving.|
As an Acorn Passenger, you can make an Oak much more dangerous. He can attack zombies that the Oak is ignoring or add up extra firepower against the same target, and has a powerful heal ability in Lumber Support that can keep an Oak in the fight for much longer. Getting three Passengers on a single Oak can apply a lot of pressure on zombies.
However this doesn't make you invincible. Acorns can take damage while riding an Oak and even be vanquished before the Oak itself. Make sure to use your Lumber Support to heal yourself as well as Oak so you can keep riding and supporting it.
