Researching alien tech is tricky. Even if you don’t accidentally create a black hole inside a test tube, knowing exactly what you’re dealing with is guesswork at best. That’s why we’re here. We’ve assembled a complete guide of everything that can be researched, what that research does exactly, and what it’ll cost you. We can’t say this will ensure the survival of the human race, but it certainly can’t hurt.

Weaponry

Weapons research is heavily dependent on – you guessed it – weapon fragments. It’s for this reason that you should never sell weapon fragments on the Gray Market and always fight every ground battle available (these are best way to obtain fragments).

Note that some research not only requires a certain set of materials, but other, specific research. For instance, you will not have the option to research Heavy Lasers if you haven’t yet researched Beam Weapons. In some cases, first salvaging the weapon from battle is required before research can even begin.

From weakest to strongest, general weapons classes are as follows: standard, laser, plasma. We’ve put “(best)” next to the strongest weapons available in the game.

Key:
B = Base Damage
CC = Critical Chance
CD = Critical Damage

Research: Beam Weapons

Requirements: 10 weapon fragments, 5 alien alloys
Unlocks: Laser Pistol (B:2,CC:30%,CD:3), Laser Rifle (B:5,CC:10%,CD:7), Improved Pistol II (Foundry)

Research: Heavy Lasers

Requirements: Beam Weapons, 5 Weapon Fragments, 5 Alien Alloys
Unlocks: Heavy Laser LMG (B:6,CC0%,CD:9), Laser Cannon (Interceptor), S.H.I.V. Laser Project (Foundry)

Research: Guided Fusion Launcher (best)

Requirements: Salvaged Battleship Class UFO Fusion Core, 75 fragments, 20 alloys, 10 Elerium
Unlocks: Blaster Rocket Launcher

Armor

Armor research works in the same way as weapons research, though the various types mean there is no “best” option. Go with what works best for each individual class or character and the role you’ve created for them.

Key:
H = Health Bonus

Research: Carapace Armor

Requirements: Salvaged Alien Materials, 10 alien alloys
Unlocks: Carapace Armor (H:4), Alloy S.H.I.V.

Research: Skeleton Suit

Requirements: Carapace Armor, 15 alloys
Unlocks: Skeleton Suit (H:3, grapple hook, increased movement)

Research: Titan Armor

Requirements: Carapace Armor, 15 alloys, 5 Elerium
Unlocks: Titan Armor (H:10, poison immunity, flame immunity)

Research: Ghost Armor

Requirements: Titan Armor, Hyperwave Communication (see “other”), 15 alloys, 15 Elerium
Unlocks: Ghost Armor (H:6, Ghost Mode ability, grapple hook)

Research: Archangel Armor

Requirements: Titan Armor, New Fighter Craft (see “other”), 15 alloys, 15 Elerium
Unlocks: Archangel Armor (H:8, flight mode)

Research: Psi Armor

Requirements: Ethereal or Sectoid Commander interrogation, 10 alloys, 10 Elerium
Unlocks: Psi Armor (H:6, Will increase of 30 for psi attacks and defense)

Interceptors

Interceptors exist to protect your satellites by engaging UFOs in direct combat. As the game progresses, it is crucial to upgrade your Interceptors to match the increased firepower of UFOs. You’ll want to research the “New Fighter Craft” as soon as possible and upgrade to Plasma Cannons.

Defense Matrix (dodge), UFO Tracking (boost), an Uplink Targeting (aim) are all available to purchase in Engineering. These are expendable items used to aid an interceptor in battle. They can turn the tide if your ship is outclassed by the UFO with which it is engaged.

Once you have well-equipped Firestorm interceptors, you have a good chance of defeating a Battleship class UFO. Doing so is crucial, as the power core recovered from the wreckage is used to create some of the most powerful weapons in the game, including the best interceptor weapon, the Fusion Lance.

Avalanche Missiles (free) and Phoenix Cannons (for a small price) are available at the beginning of the game.

Key:HC = Hit Chance
R = Range
FR = Fire Rate
D = Damage
AP = Armor Penetration

Research: Heavy Lasers

Requirements: Beam Weapons, 5 Weapon Fragments, 5 Alien Alloys
Unlocks: Laser Cannon (HC:85%,R:Short,FR:Rapid,D:Low,AP:Medium)

Research: Phoenix Cannon

Requirements: Experimental Warfare research
Unlocks: Phoenix Cannon (HC:95%,R:Short,FR:Rapid,D:Low,AP:Low)

Research: Plasma Cannon

Requirements: Light Plasma Rifle, 30 fragments, 10 Elerium
Unlocks: Plasma Cannon (HC:85%,R:Long,FR:Medium,D:Medium,AP:High)

Research: New Fighter Craft

Requirements: Salvaged Alien Nav Computer, UFO Power Source, 75 fragments, 10 alloys, 10 Elerium
Unlocks: Firestorm Interceptor and Hover S.H.I.V.

Research: EMP Cannon

Requirements: New Fighter Craft, Plasma Cannon, 20 Elerium
Unlocks: EMP Cannon (HC:100%,R:Short,FR:Medium,D:High,AP:High)

Interrogations/Autopsies

Whenever you defeat a new enemy type, your research team can perform an autopsy on the corpse after the battle. If you use the Arc Thrower item to capture the enemy alive, your research team can perform an interrogation (after which, they can perform an autopsy on the same subject).

In most cases, interrogations only give you research credit in a specific area. This credit simply speeds up research time related to said area. Interrogating a Sectoid Commander and an Ethereal provide additional rewards.

Note that “projects” refer to Foundry undertakings, and have no effect until you build a Foundry and spend the required resources to complete the project. Also, you cannot interrogate or stun robots, so don’t bother trying.

Foundry Projects

The Foundry is a facility that can be constructed once you’ve researched “Experimental Warfare,” which has no prerequisites. It is here that you can improve all aspects of your XCOM capabilities – at a cost, of course. Unlike the research done in laboratories, which requires scientists, research done in the Foundry requires engineers.

Note that the credit cost is not included here, as it varies depending on the research you’ve done and/or satellite coverage bonuses.
