Push units into hazardous areas such as a Spring Trap, a Mega Mine or high-damaging buildings like the Crusher to do more damage to them.
Push Traps can be carefully placed to push enemies into another Push Trap. This is best done to high value Troops, like the Boxer Giant, to effectively stall an attack.
You can purposefully upgrade only some push traps and use a higher level push trap to push units onto a lower level push trap. The higher level push trap pushes more troops than the lower level push trap, effectively splitting up your opponent's units as some units cannot be pushed by the lower level one.
Offensive Strategy
When going against this trap, try to use one expendable unit, such as a Raged Barbarian, to trigger this trap.
The trap remains hidden before triggered, so the player would have to predict where it is
You can use the Battle Machine to trigger Push Traps as it does not affect it.
Upgrade Differences

At level 3, the arrow turns to metal and the wood is darker.
At level 4, the corners are now metallic.
At level 5, the corners connect through metallic stripes.

Trivia
Although the Push Trap is rotated 90 degrees each time, it uses the Air Sweeper's smaller rotation icon (the Air Sweeper rotates 45 degrees each time), rather than the Walls' right angle rotation icon.
