In a post on Bethesda's website the game's director John Johanas commented on the new upgrade system. Even so The Evil Within 2 will feature deep customisation and crafting. Green Gel will be used only for Sebastian's upgrades, and Weapon Parts will be for your weapons, obviously. Play it smart and you might not die too many times.
The weapons customization is no less extensive, including upgrade options for ammo type, ammo capacity, reload time, and fire rate.
Health - Dropping some Green Gel in the Health tree will give you the chance to survive an attack that might have otherwise killed you. Health, for instance, won't just keep you from succumbing, but can also increase your life gauge altogether, as well as letting you take attacks better than you normally would - something that's quite handy when it comes to staying alive.
Stealth - In addition to an increased movement speed while crouching, the Stealth tree can allow you to perform Sneak Kills from around a corner while in cover. Upgrades within these skill trees are numerous, but include recovering more health from healing items, reducing reticle sway when firing weapons, and the chance to automatically use a Medical Syringe when taking fatal damage.
Athleticism - For the Sebastian on the go, the Athleticism upgrade options will let you increase your Stamina Gauge and give you a chance to auto-avoid certain types of incoming attacks. However, it looks as if the next entry in the series will provide a customization system that's a lot more expansive and adaptable than its predecessor, as Bethesda has released a brand new trailer detailing how the management of the main character and his sundry arms is going to work. As in the first game, you'll also be able to customize your weapons and craft traps so you don't have to rely on the same pistol the whole way through your adventure. "You don't have to rely exclusively on what you can scrounge up in the world". Secondly, Bethesda has put a much "heavier emphasis on player choice" so you can absolutely customize your play style to however you prefer to handle the horrors within the game. You can tweak these with Sebastian however you see fit, depending on what sort of play style you want with him. You'll have to take it back to a workbench and craft there, or use significantly more resources to craft on the spot.
