XCOM: Enemy Unknown Research Guide – Xenobiology, Engineering and Weapon Manufacturing
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 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)
Requirements: 10 weapon fragments, 5 alien alloys
Unlocks: Laser Pistol (2,30%,3), Laser Rifle (5,10%,7), Improved Pistol II
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
Requirements: Beam Weapons, 5 fragments, 5 alloys
Unlocks: Scatter Laser Shotgun (6,20%,9), Laser Sniper (6,30%,9)
