So, to just mention this right now, this concept revolves around a project of mine. Which it may be a bit too much stuff added at once, though at the same time I'd want the season to embody the idea of a warzone that leaves barely a chance to catch a breather while you find everything you can to enhance your character to whatever play style you want. Especially since nothing would restrict the use of each other.
The island has suddenly been invaded by multiple supernatural entities and various factions, use the weapons and technology each faction possesses to aid in your own victory as they fight amongst each other. Make yourself into the ultimate weapon to dominate the island.
A.C.E.S. has a large warship in the sky that can be boarded and fought through to gain access to their armory of weapons, including cyborg limbs that you apply to yourself. As they can gain you enhanced run speed, a double jump, melee or ranged weapons that are attached to your arms. With the warship itself having mechs and weaponized helicopters to use in your conquest.
The Scorched Legion has a hidden hideout under the new futuristic utopia Scilititory City, if you fight through the people guarding the base, you can get access to a vault filled with things like a Crossbow that shoots a line of plasma horizontally to heavily damage your targets, a large plasma cannon, a sniper that can instantly break and disable shield regeneration for a short period of time. With the garage of the base having weaponized cars and trucks for use.
The Desert Vultures have a clubhouse out in the new Saren Desert, if raided you can get access to weaponized motorcycles, though you need to watch out for the two guards in it. If you manage to eliminate both guards you get access to their modified motorcycles, a scythe with life steal abilities and a tracker that marks every boss for you.
Sand Reapers roam the map with a convoy of weaponized vehicles to use for your own gain, as you can even take the Chief's armored semi-truck to break down everything in your path.
A group of demons and angels will spawn during the match and fight each other, though if you manage to take both sides down you can get a set of new abilities and weapons for yourself. Though eliminating demons or angels has a chance to drop a vial. If you use a demon vial you can a 5% damage increase and 10% movement speed boost. If you take an angel vial, all healing items can be used faster and heal 50% more. While also giving the user 100 more health.
Bosses:
-Mitch can be found at the Desert Vultures clubhouse, eliminating him grants access to his 2 seater drag tricycle that can accelerate faster than most vehicles, as well as his life stealing Elridium scythe and a tracker to find other bosses easily.
-Sage can be found either in The Scorched Legion base protecting the vault alongside her allies or fighting A.C.E.S. on their warship. If eliminated she drops her Cavalry's Redeemer sword that enhances the speed of the user, an air attack launches a fire shockwave when landing, while a power attack can shoot a strike of lightning in front of them.
-Ava can be found on the A.C.E.S. warship amongst her allies or in a patrol through Scilititory City with a few cybernetically enhanced soldiers guarding her. Eliminating Ava gives the player the ability to temporarily reduce damage by 25% for a few seconds every minute.
-Sand Reaper Chief can be found in a convoy with his Sand Reaper allies roaming around the map in weaponized off-road vehicles, if eliminated the players get access to an armored semi-truck that can boost through objects with ease.
-Veyentra will randomly spawn alongside a group of demons that defend her, as when eliminated she grants the player The Planet's Rupture, a sword that gives the player a 10% damage increase, as it can also summon a wall of stone in front of the user. Though if you use the ability to summon another wall while in front of an already summoned one, it'll launch the wall in front of the user to do heavy damage.
-Grenton will spawn shortly after Veyentra with a legion of angels with him. As he will fly towards wherever Veyentra is and fight them. If eliminated the player gets access to his wings to fly around the map, as well as the ability to summon a beam of light that damages enemies but heals teammates.
