Notes

• Weapon Fragments, Alloys, and Elerium are used to manufacture most items in the game. This is why their resale value is so low and why obtaining a precise number required for each project is so difficult - the base requirements are listed but they can vary due to variances in the number of engineers, workshops, etc. Unless you are seriously strapped for cash, try selling something else instead.
• Second Wave's Marathon doubles the requirements for everything.

Unlisted devices

• "Elevator Beam" - found mainly on Battleships, these odd floor-bound pod pairs quickly and safely raise and drop the user between their repsective levels. Standing on a pod prevents their use, and can keep an alien on a lower floor, giving you a well-defended position.
• Abduction Pod - seen functioning in the opening cinematic, they release some kind of coagulating snare substance, cocooning humans for capture. Despite the many you'll encounter, they give no alloy resources for XCOM.
• Syringe - sometimes when awakening a Thin Man squad, one can be seen wielding some kind of needle, often embedded in a cocooned human, obviously taking blood/tissue samples.
• Plasma Bomb & Nodes - You'd think you'd get some Elerium from a plasma device that can wipe out a small town.
