Staying alive requires constant attention to your health and armor. These pickups are scattered generously throughout the levels:

- Small Health Vial: Restores 1 HP. Often found in groups.
- Large Health Pack: Restores 50 HP. Crucial for recovering from heavy damage.
- Small Armor Shard: Restores 1 Armor. Often found in groups.
- Large Armor Vest: Restores 100 Armor. Provides significant damage reduction.
- Mega Health: Restores 100 HP and can temporarily boost your health above 100 (up to 200). Very rare and valuable.
- Mega Armor: Restores 100 Armor and can temporarily boost your armor above 100 (up to 200). Also very rare and valuable.
Armor absorbs a percentage of damage before your health is affected. Always try to maintain a good balance of both. Don't hesitate to backtrack slightly to pick up health or armor if you're low, especially before entering a major combat arena.
