Extant Existence
Extant Existence, also known as Endless or just Extant, is an 'Endless' wave-based gamemode focusing entirely on the combat, and takes place in one large arena that changes colors every 10 waves.
As waves progress, Enemy's stats increase, with the affected stats including Health, Armor, and Attack Power.
Every 10 waves these stats increase heavily for one wave, and then go back down part of the way, causing an effect of spikes of difficulty with an overall trend of slow difficulty increase. This trend stops at wave 50 where the numbers only go up gradually, and do not spikee before coming back down.
Implants are regularly given every few waves, where you can pick one of two random implants, or level up an existing equipped Implant.
Secondary Weapon Mods are also given out every few waves like Implants, and can be used to level up or switch out your equipped secondary weapon.
There is a Shop that functions differently in extant, which replaces a random implant & the grenade capacity increase & refill options with instead having a Weapon Mod section, Shell Upgrade section, and a Neuralboost section.
There are also Pickups in the arena, which include a pickup that restores all Health, gives a grenade, ammo refills, cooldown resets, and an infinite ammo pickup.
