Enslaved: Odyssey to the West/Upgrades

As you make your way through the game, collect every Tech Orb you can find to upgrade your equipment. Just before the boss fight at the end of Chapter 2, Trip will tell you she can upgrade your equipment and an option to go into Trip's Shop will appear at the bottom of the Command Menu.

Combat
These upgrades are all to enhance your melee fighting abilities.

Health
The two types of health upgrades are extending the amount of Monkey's health and giving him regeneration powers. You must purchase the levels of each upgrade in order, and they get better (and more expensive) until they max out.
 * 1) Health Extension: Increases Monkey's total health.
 * 2) Health Regen: Monkey's health will regenerate over time until full.

Shield
Shield upgrades improve your shield. You can purchase upgrades to increase the rate the shield recharges and increase its resistance to projectile fire and melee attacks. You must purchase the upgrades in one of the three areas in order.
 * 1) Shield Recharge: Reduces the time the shield takes to recharge.
 * 2) Shield Strength: Increases the number of shots Monkey's shield can withstand.
 * 3) Block Strength: Increases the number of strikes Monkey can block before taking damage.

Staff
These upgrades concern the projectile capabilities of your staff. Here you can increase your ammo capacity, shot strength and add special attacks to your ammo. Each level in the six paths must be purchased in order if there is more than one:
 * 1) Fire Rate: Increases Monkey's firing rate.
 * 2) Ammo Increase: Increases the maximum ammo Monkey can carry.
 * 3) Stun Time: Increases the stun duration of enemies hit by a Stun Blast.
 * 4) Stun Effect: Causes Stun Blasts to explode, affecting multiple enemies with one shot.
 * 5) Plasma Penetration: Plasma Blasts go through enemies and can hit others with one shot!
 * 6) Plasma Penetration: Doubles (level 1) or quadruples (level 2) the damage a Plasma Blast does to an enemy!
