GZ RPG adds persistent character progression to Factorio.
Players gain XP from combat, research, exploration, and supported GZ systems. There are 999 levels, with progression slowing significantly at higher levels.

Choose from four roles:

Role        Focus
Tank        Strength, durability, stamina
Sniper      Agility, damage, mobility
Support     Balanced progression
Engineer    Willpower, luck, crafting and utility

Changing roles affects future stat growth only. Existing attributes are retained.

Permanent attributes include Strength, Agility, Willpower, and Luck. These contribute to derived stats such as health, mana, stamina, movement speed, damage, and crafting speed.

Active abilities unlock as you level:

- Sprint — Level 10
Increased movement speed while consuming stamina.
- Magic Eye — Level 20
  Creates temporary remote vision at the cursor.
- Blink — Level 30
  Short-range teleport toward the cursor.
- Psionic Blast — Level 40
 Knocks back and briefly stuns nearby enemies.
The Psionics technology line improves Magic Eye, Blink, and Psionic Blast.

Combat XP is awarded for enemies personally killed by players. Research XP is based on science consumed and is shared across the force.
GZ RPG integrates with the wider GZ suite through GIZMOD APIs for UI, milestones, statistics, events, and cross-mod effects.
