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[edit | edit source]

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[edit | edit source]

Basic[edit | edit source]

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.

Refining[edit | edit source]

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.

Turrets[edit | edit source]

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

Heavy Weapons[edit | edit source]

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.

Explosives[edit | edit source]

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.

Robotics[edit | edit source]

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.
