Speed Boost
A walkable pad pushes you in the direction you face when placing it.
Mechanics
Section titled “Mechanics”Players, 
zombies and the 
Reaper receive the
push regardless of allegiance. Thrown 
TNT also receives it, but projectiles
and placed TNT do not. The push stops affecting thrown TNT once it starts exploding. Crossing
sideways or walking against the pad does not change its push direction.
Check the direction before placing a pad at your exit. Aim it outward because the push also applies to attackers.
Unlocking
Section titled “Unlocking”In the Other branch of the structure trees, spend
1 structure point from your upgrade points
at level 4 or higher to unlock the build item. No earlier structure upgrade is
required. Choosing it locks out the 
Anti Structure Pad and
the 
Honeycomb for that life, even if you earn more structure points.
Each placement charges the resource cost shown above.
