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.

OverviewEdit

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.

TechnologiesEdit

BasicEdit

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.

RefiningEdit

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.

TurretsEdit

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 WeaponsEdit

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.

ExplosivesEdit

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.
