Unlike many RPGs, Far Cry 3: Blood Dragon features an automatic skill progression system. As Rex gains experience (XP) from completing objectives, killing enemies, and performing takedowns, he will automatically unlock new abilities at predetermined XP milestones. There's no skill tree to navigate or points to allocate, ensuring a streamlined and focused gameplay experience. This means every player will eventually have access to Rex's full suite of cyber-commando skills.

These unlocks include enhancements to various aspects of Rex's combat and stealth capabilities. For example, you'll gain the ability to perform chain takedowns, execute takedowns from above, or perform takedowns while sliding. Other unlocks might include increased health, faster healing, or improved weapon handling. The game will notify you each time a new ability is unlocked, often with a brief tutorial on how to use it. Pay attention to these notifications, as they introduce powerful new options for dealing with enemies. This system ensures that Rex continuously feels more powerful as you progress through the game.
