Potential Items/Equipment

Underwater Exploration Submarine Power-ups/items

Small treasure item ideas:

• Bottles (with either maps to side treasures or clues for the diver puzzles)
• Jewels, gold, etc
• Treasure chests

Submarine Market:

• Hull upgrades and repairs
• Speed, acceleration, maneuverability, energy, scanner range (visible range), and fire rate upgrades
• Ammunition
• Reverse engineering and repairing options for recovered items--very important.

Purchasable

• Claw: Raise and lower the claw to pickup items off the sea floor.

• Spotlights/Searchlights: used to see in very dark places or to make minor treasure items on the seafloor "sparkle"

• Smokescreen: blind sea life temporarily.

• Torpedo Launcher: it is the primary weapon versus hostile sea life. It has ammunition, and a slow refire rate.

• Nano-tech: repairs the hull slowly over time for a limited time (one use per item)

"Magical" or recovered items (The energy consuming items have a common power source):

• Grappling claw: fire a claw at objects to grab them in harder to reach places. (Replaces normal claw)

• High intensity searchlight: much wider radius, brighter, and can force the large deeper dwelling creatures to recoil (otherwise they are impassable guardians)

• Pressure equalizer: Allows you to reach lower depths without harming the diver.

• Depth charge launcher: (has ammo) clear large amounts of loose rubble or harm enemies beneath you.

• High yield torpedo launcher: (has ammo) can clear rubble at a distance. Higher yield torpedoes do increased damage.

• Heat shield: allows passage through magma, but consumes a recharging energy bar, and can be used as a damage buffer feature for normal sea life encounters.

• Drill: destroys large, fairly solid walls of ice/rock on contact.

• Booster: gives a short burst of speed (used to overcome extreme current). It uses a recharging energy bar.

• Shock wave generator: push all objects away from you (has energy bar) (especially useful for puzzles either involving moving objects rapidly from one area to another, detaching sea life from the sub, or repelling explosive mines)

• X-ray scanner: allows you to see items behind walls (which can ultimately be drilled to or demolished), and see items that fish have swallowed.

Dive suit equipment--the submarine should be able to carry some addition ammunition for the diver too.

• Knife: cuts rope or other obstacles (not sure that it can be an effective weapon underwater)

• Sound gun: annoy/repel different sea life based on the sound/frequency you project.

• Oxygen tank extensions

• Antidote: is there poisonous sea life here?

Recoverable items--some of the recovered items for the diver and sub could be obtained simultaneously (heat shield, pressure equalizer, etc):

• Harpoon gun: defeat small enemies, hit distant switches--(has ammo)

• Personal shoulder light: illuminate what you face, treasure sparkles, and sea creatures are alarmed of your presence

• Electromagnetic boots: scale metallic surfaces, walk on ceilings, etc within sunken ships/other ruins. (could use energy)

• Personal grapple device: fires a rope & claw (via harpoon gun?) to hoist yourself up onto predefined foliage/ropes/loose or porous materials (large amounts of seaweed, for instance). No ammo.

• Booster pack: simplistic "jet pack" that consumes your Oxygen with use (Oxygen is used as a means of propulsion).

• Personal heat shield (uses energy)

• C4 explosives: (has ammo) clear a small amount + size of rubble and create a shock wave.

• Personal pressure equalizer
