XCOM: Enemy Unknown Research Guide – Xenobiology, Engineering and Weapon Manufacturing

By   /   4 years ago


When you’re dealing with an alien invasion, you’re bound to find some weird technology that would water the mouths of those researchers and scientists.

Of course, it doesn’t necessary have to end well, and we’ve seen plenty of movies (District 9, Transformers, and many more) that suggest that.

Thus, it’s important in XCOM to do your research with whatever alien related stuff you find. This essentiality is actually a large part of the development system of the game.

The Research and Engineering of XCOM allows you to develop new weapons, create badass defense armors, attain credits, and much more. But because of the risks, you’re best doing so with a guide to get aid from, and we have exactly that.

Weapons

Weapons in XCOM are researched by finding alien weapon fragments during fights. It’s thus essential not to sell them on the Grey Market, and opt to fight all the battles available to attain as many fragments as you can.

In addition to simple fragments, you may need specific materials, such as alloys or other weapons. Some researches have to be carried out before the next ones can as well.

The following are the researches and their rewards.

Note that stats for the unlocked weapons are displayed as: (Base Damage, Critical Chance [%], Critical Damage)

Beam Weapons
Requirements: 10 weapon fragments, 5 alien alloys
Unlocks: Laser Pistol (2,30%,3), Laser Rifle (5,10%,7), Improved Pistol II

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

Precision Lasers:
Requirements: Beam Weapons, 5 fragments, 5 alloys
Unlocks: Scatter Laser Shotgun (6,20%,9), Laser Sniper (6,30%,9)

Light Plasma Rifle:
Requirements: Salvaged Light Plasma Rifle, 40 fragments, 10 alloys, 5 Elerium
Unlocks: Light Plasma Rifle (5,10%,CD7)

Plasma Pistol
Requirements: Salvaged Plasma Pistol, 40 fragments, 5 Elerium
Unlocks: Plasma Pistol (3,20%,4), Improved Pistol III Project

Plasma Rifle
Requirements: Salvaged Plasma Rifle, 40 fragments, 10 alloys, 5 Elerium

Armor

Armor researches work in a similar manner to the weapons one. However, instead of weapon fragments, your focus is mainly on general material and lower-grade armors for advanced researches.

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

Skeleton Suit
Requirement: Carapace Armor, 15 alloys
Unlocks: Skeleton Suit (HEALTH +3, grapple hook, increased movement)

Unlocks: Psi Armor (HEALTH +6, Will increase of 30 for psi attacks and defense)

Interceptors

Interceptors are basically your anti-UFO fighters to keep your satellites safe. As you progress onwards, you’ll fight against tougher UFOs. Thus, it is extremely essential to research and upgrade your Interceptors as soon as you can.
