Starting with the Abhuman, these would be a rather unique glass in the fact they come in 3 types, goat, cat, dog. all three are normal human sized but have the same special, hightened senses, where for a bit of time they automaticly point out special enemies giving allies a 5% bonus damage against said enemies.
Other wise, they come in three personality types, Smart, dumb, and animal sounds.
Weapon wise, they have a basic set of weapons, with a large amount of fist type weapons like claws and metal fists.
Grenade slot: they throw standard grenades.
Techpriest
We all know the toaster lovers, why not play them. Tech priests would be a low health option with a hacking grenade ability that allows them to turn any explosive on the map that has a servo skull into a proximity mine, though their device has a a charge and only healing stations refill it. (by default you can hack 10 items before needing a recharge.)
Ability wise they can deploy servo skulls, these very based on their melee weapon. choice from a basic one that just scans the area, to one teathered to the priest healing them rapidly. other examples are one with a laser pistol in its eye, another that acts as a distractions, and a final one that just flies into things and explode. these are once again based on their melee weapons.
Speaking of their melee weapons, instead of swords, hammers and other things they have a set of extra arms. these come in different types from ones that light enemies hit on fire, to others that can heal allies by draining the users hack charge. EAch changes you [F] Ability.
Ratling
Short, angry and very good at range infact they completely lack a melee weapon, to make up for this they have a unique heavy rifle slot which is snipers and long range explosives. their secondary slot can have any pistol class weapon in it.
for abilities their grenade is a set of 4 single use ammo boxes, and their F is an “aim assits” that aims for weakpoints, that is charged by heating heads with out it. every 2 headshots gives 1 charge to their ability. up to 10 charges once the ability is active if they have ammo they will fire upto 10 shots hitting anything nearby in the head/weak point, these shots will not overkill so no stacking unless it is on a strong enemy.
