Robo Stomp is the first ability for the Z-Mech and Party Mech in Plants vs. Zombies: Garden Warfare 2. When used, the Z-Mech will stomp on the ground, releasing a shockwave that will toss away all nearby plants and deal 75 damage in an area of effect. It recharges relatively quickly, thus making it an effective ability to use while other abilities are still recharging in the same time while massing out other plants.
Plants getting too close for comfort? Good thing you're in a giant robot with huge metal feet.
This ability is fantastic against close range plants, such as Chompers and Weeds, as this will not only push them back and fling them in the air, but it will also either take them out or severely damage them so you can finish them off with Missile Madness or your Robo Laser/Party Robo Laser. However be wary of using this ability when there is a rooted plant shooting at you, as you stop moving while using this ability and you cannot use Explosive Escape while this is in use but if there is a rooted plant directly next to you, using this will unroot it, allowing you to finish it off with ease. This almost identical to the Z7 Imp's Zomni-Blade, so these strategies also apply to this as well.
You shouldn't worry too much about this because you shouldn't even be close to the Mech at all unless you're a Chomper who's chomping it from behind, but Mechs can flank you and use this so watch your surroundings.
- This could be a reference to the stomp attack used by the Zombot as they are both stomp attacks used to attack plants and are used by large robots piloted by a zombie.
