2) Defense, and offense (screw mobility, I'm just interested in killing everything today).

Active Shielding:
Shields get a passive bonus of minor damage reduction and damage over time to enemies that are in contact with them. Melee hits with the shield will also do more fire damage.
When used actively, the plasma shield projected onto the physical shield will be overcharged and explode outwards, sending a blast of superheated plasma out in front of, and to a lesser extent around the shield. This blast does high fire damage, and has a medium knockback. It will slow down the players movement when used, and also apply a kickback, negated if on the ground and stationary, otherwise pushes the player backward, especially in the air (though with some RNG so not completely predictable just where backwards you'll fly).
During the first half of the cool down after using the active ability, the passive benefits will be lost.
Breakthrough:
Directs extra power into the suits mobility systems. Movements are much faster and total speeds increase noticeably for a short period both on the ground and in the air. Jets will be visibly used even when moving on the ground if moving forward to add extra speed/energy into the charge. If flying, jets will overcharge and allow for faster flight and greater acceleration, though only forward (direction can still be changed, but strafing/reversing wont' benefit from the speed boost).
During this period, the shield is raised and brought in front of the suit, there is a knockback dealt to any enemies hit with it, along with some damage, relative to the suits current speed. A slight speed loss will also be incurred upon contact, relative to the enemies mass.
When charging, the shield will be held in and bashed out upon contacting an enemy, this action will noticeably increase the damage dealt to the hit enemy, and lower the movement penalty from that hit to the player. The arm will take a second to be returned to its fully ready position, this timer will reset if any new enemies are hit during this time. So the effects are higher if only hitting a few key enemies, but you still can charge through warms of smaller enemies if you want.
Power is restricted to only mobility systems, so any weapons or other abilities, or self repair system that rely on power will not operate during this abilities active time.
5) Gauss Cannon:
A large anti armor cannon, it has a very fast projectile speed, with a large amount of damage on direct hits, and a moderatlely damaging aoe blast around the hit point. The fire rate is slow, and in order to fire a certain amount of energy must be available in the suit (and will be consumed) beyond normal ammo limits. This is a large powerful cannon normally used for dealing with heavy armored vehicles, as a result is is very powerful, but also has considerable recoil and is very heavy, slowing the suit wielding it. When fired, a considerable knockback is applied to the suit, throwing them backwards if in the air, and just pushing them back a few feet and stopping forward motion when on the ground. If zooming/aimed in while on the ground, the suit will go into locked down, allowing for more accurate fire and no knockback, but also locking movement, and limiting rotation to the current forward ark when the aim was started.
6) Twin bolter cannon: (think storm bolters from 40k terminator armor)
A double barreled cannon firing small explosive projectiles at a decent rate, though somewhat inaccurately. Powerful, but with a long reload time and unable to hit targets reliably beyond a short distance.
Fortress Wall:
A MASSIVE shield, it slows the user down, but provides almost completely coverage of the frontal arc and offers significant damage reduction too all shots it takes in its protected ark. If used as a mellee weapon it is very slow to hit targets, though fairly powerful. If you use it while free falling onto an enemy it gets a bonus to its slam damage, and can squish most enemies outright if brought down like this.
7) The Walking Rampart.
It is a very large heavy suit, covered in large amounts of armor, thick blocky plates, making it look like a veritable walking tank. Equipped with its massive frontal shield and Gauss Cannon, it is often seeing sitting back from the battle blowing up groups of enemies, or tearing into larger tougher targets. For the enemies that manage to get close to it, they may find its massive bulk brought to bear, charging down on them. This sight is often described as being akin to having a castles walls charging towards you, and has been the last sight many have seen. Unfortunately it can only move quickly for short bursts, so if surrounded and outnumbered, it may be brought down if it doesn't have sufficient support from other frames.
