Perk System 2.0
- The Perk Pro system has been upgraded
- There is now 2 options a perk can advance to.
- Both require different challenges to unlock
- Once the desired Pro version is unlocked, the player can select that as their “Perk Pro”.

- For example Perk slot 1 has the perk called Speed
- Speed – Reduces the time taken to aim down the sight
- Pro I – Swaps weapons faster
- Pro II – Throws equipment faster
- Will be returning with vast improvements.
- Difficulty is no longer based on how long the bots take to start shooting.
- Bots now have an advance AI system
