The game actually puts an emphasis on using the environment to kill
enemies since things that are destroyed tend to burst outward like you hit a grenade hiding
within it which works surprisingly well
against enemies standing next to
certain bits of the environment.
For example, players might try a
certain Pikmin type
against a
certain enemy type and lose a few, but players can always regenerate these Pikmin, so the only thing lost is time, which is a factor because of the time limit
within the gameplay.
