World 2 isn't releasing I just wanna share the concept and anims
Basically BCU has a feature called summon where you can summon units. There are two here. The first one picks a random location to spawn the blockhopper (similar to how surge works). That blockhopper then sits there with 0 speed, like the doge base, and its a self destruct unit. Once you get too close to it, it'll reveal itself, self destruct, and summon the walking version of the enemy. That enemy is the one you see running and doing wave attacks.
