Gravity Smash is an ability for the Space Cadet in Plants vs. Zombies: Battle for Neighborville. When activated, Space Cadet flies up into the air for 3 seconds and then crashes down dealing damage to enemies.
Move faster while Gravity Smash is active.
Increases the player's movement speed by 50% while using Gravity Smash.
Gravity Smash is best as a finishing move, as it usually won't do enough damage to completely destroy an enemy, similar to Fung Fu. However, this ability should be able to completely destroy enemies with low health like Night Cap and Acorn if aimed correctly.
As an alternative, this can be used to semi-escape a sticky situation by catching your opponents off-guard. If you're being attacked, use this and they'll attack where you were, not where you are, to hopefully allow you to escape. But keep in mind if you do this that you can't run away easily while Gravity Smash is active.
