Research

Research Tree

Research leads to new advancements in Revenge of the Titans, allowing new buildings to be unlocked. Each research has a prerequisite that must be unlocked first before moving on to the next one, some technologies have up to 7 prerequisites.

Overview

After each mission one unlock will be allowed, whether this is in the Technologies, Delivery, or Buildings section. There are a total of 33 Technologies, 7 Deliveries, and 33 Buildings, making a grand total of 73 available research items. There are 50 missions, so only 50 items will be researched, or roughly 2/3 of them.

Technologies

Basic

The basic resarch that opens up certain fields of technology.  Chemistry research is geared towards explosives and armor.  Particle Physics focuses on Electricity-based attacks, shielding and add-ons.  Xenobiology focuses on raw damage and special attacks.

Applied

These Research items give a permanent boost to every building. They consequently are often very powerful, but have numerous prerequisites.  Many require the Extra Coffee Delivery bonus completed.

Deliveries

These Research items give an immediate bonus, but has no lasting benefits.  (Except for leading to other research items)

	Special Supplies	Reinforcements			Gain one of each powerup

Buildings

Refining

As a general rule of thumb, remember that extraction technology are never required ; you can beat the game with basic refining; without feeling money-starved.

Image	Name	Prerequisite	Required for	Description	Effect
	Refinery	None	·Efficiency ·Reprocessor ·Collector ·Droid Factory	Research of the extraction and refinement of valuable crystal deposits, to fund the war effort.	$10 / 3 secs
	Reprocessor	·Refinery ·Collector ·Efficiency ·Extraction Tuning	·Extraction Calibration		+20% Income Generated.
	Collector	·Refinery ·Efficiency	·Extraction Tuning ·Extraction Calibration ·Reprocessor		+1 Extraction Rate

Turrets

Turrets are your main damage source in Revenge of the TItans.  You will need most, if not all, of these to beat the game.

Image	Name	Prerequisite	Required for	Description	Effect
	Blaster	None	·Multi-Blaster ·Blast Cannon ·Spreader Cannon ·Assault Cannon	Fires Blaster Rounds. Ineffective against armoured targets.
	Heavy Blaster	None	·Blast Cannon ·Assault Cannon	Efficiency increases for basic blaster technology to produce armour piercing blasters.
	Multi-Blaster	·Blaster ·Cooling Tower ·Multibarrel Technology
	Blast Cannon	·Heavy Blaster ·Phase Amplifiers
	Spreader Cannon	·Blaster ·Positron Beam Splitter ·Alien Anatomy	·Assault Cannon
	Assault Cannon	·Phase Amplifiers ·Spreader Cannon

Heavy Weapons

Heavy weapons are all long-ranged turrets, with powerful armaments.  However, production is limited, so it's worth building your defences around them. The laser is practically mandatory to deal with flying pests on Saturn.

Image	Name	Prerequisite	Required for	Description	Effect
	Rockets	·Chemistry ·Ballistics ·Explosives ·Explosive Shells		A long-range, high-powered rocket launcher.  Massive splash damage. Can damage your own buildings
	Laser	·Particle Physics ·Lasers ·Optics		A long-range laser.
	Disruptor	·Xenobiology ·Particle Physics ·Alien Anatomy ·Forcefields ·Nuclear Fusion ·Reactor		Emit a destructive shockwave from the turret ; damage your buildings without Disruptor Shielding

Explosives

Mines are good way to release the pressure when there are too many titans, or to finish off stray Titans.  Mines cannot be sold and are not reclaimed after a mission.

Image	Name	Prerequisite	Required for	Description	Effect
	Mines	·Chemistry ·Explosives	·Cluster Mines ·Blast Mine		Explodes when medium to large titans step on them.
	Cluster Mines	·Chemistry ·Explosives ·Mines	·Blast Mine		Explodes when any ground titan, including small ones, steps on them.
	Blast Mine	·Chemistry ·Advanced Explosives ·Barometrics ·Cluster Mines ·Explosives ·Mines			Explodes after 5 second when activated ; effectively a mini orbital strike.

Robotics

Tanks and droids are a good mobile force to complement your turrets. The Repair Drone is an awesome but expensive way to keep your defences in shape.

Image	Name	Prerequisite	Required for	Description	Effect
	Droid Factory	·Refinery ·Automation ·Efficiency ·Robotics			Periodically creates small droids that chase and attack titans, can target small titans
	Tank Factory	·Refinery ·Automation ·Efficiency ·Robotics			Periodically creates tanks that chase and attack titans
	Repair Drones	·Refinery ·Automation ·Efficiency ·Robotics			Periodically creates repair drones that repair your buildings

Misc.

These buildings have unconvential effects, which can radically change your strategy.

Image	Name	Prerequisite	Required for	Description	Effect
	Capacitor				A player-controlled turret; stuns Titans being attacked; Only weapon effective against Wraiths
	Decoy	Alien Psychology			Attracts and soothes titans; Acts like a second 'target' for the Titans; Only 1 per level is allowed
	Shield Generator	Forcefields			Give additional shields to your buildings
	Tangleweb	Exotic Textiles			Slows down Titans that walk over them; They are destroyed by Explosives.
	Scarecrow	Xenobiology Alien Psychology			Scares Titans away from an area.
	Cloaking Device				Make your buildings invisible to Titans

Add-ons

These buildings augment nearby turrets, making them much more effective at killing titans.

Image	Name	Prerequisite	Required for	Description	Effect
	Cooling Tower		·Multi-Blaster		Increase your turret fire rate.
	Battery		·Capacitor		Increase your turret ammo capacity
	Reloader				Increase your turret reload speed

	Reactor		·Disruptor		Increase your turret damage.

Barricades

These buildings serve as a buffer between your weak buildings and the titans.
