No, it's an alien class, as I clearly stated above...
I meant would the human player get switched to A.

Anyway, Grapple:
Humans can use it to grapple on anything: walls, cielings, clouds, stars, skyboxes, aliens.
Primary attack grabs hold of objects, walls, players etc. If players are grabbed, if primary attack button is released, user is flung at the grappled player. If secondary attack button is clicked while primary is still pressed, player grabbed gets flung to user.
Secondary attack pokes eyes out of players, making them blind until they reach a booster/medpad by hearing/orienteering. Also gives near to killing damage (% of hp).
Tertiary attack sterilises target; cannot evolve or build. Limps for rest of life. Cannot wallwalk or jetpack, jump or sprint. Cannot have kids.
