Dr. Shen, XCOM's head of Engineering
Main Engineering

In XCOM Engineering you will manufacture items that improve your capacity to repel the alien invasion.

Dr. Shen

Dr. Shen is the Chief Engineer at the XCOM base. He will notify the Commander of any news related to Engineering, as well as providing scientific advice during combat missions.

Resources

Three types of resources are needed for manufacturing in XCOM:

Engineers available versus cost savings

If you have more Engineers than the minimum required, they provide a cost discount. The discount increases quickly at first, then slows. It never goes below 50% (see graph). Rounding down, the formula is:

XCOM 2012 Engineers versus Savings formula corrected.png
  • When the current number of engineers equals the minimum needed, the term in parentheses becomes "2", cancelling the 1/2.
    • At twice the number of engineers, the cost is 75.0 % of original. So with 10 engineers, a satellite (Base Cost §100) costs §75.
    • At three times the number of engineers, the cost is 66.7 %, after which the discount slows down.
    • At five times the number of engineers, the cost is 60.0 %. With 25 engineers, the satellite costs §60.
    • At ten times the number of engineers, the cost is 55.0 %.
    • At twenty times the number of engineers, the cost is 52.5 %. With 100 engineers, a satellite costs §52 (since the final cost is rounded down).

Other resource costs (corpses, etc.) are not discounted.

  • The North American continent bonus gives another 50% discount to aircraft and aircraft weapons.
  • The Asian continent bonus gives another 50% discount to SHIVs.

Workshops and Bonuses

For information on the structure, see Workshop.

  • 2 Workshops adjacent to one another will give a 7% discount on building items.
  • For a 3*3 square with 9 workshops, you will get 12*7% = 84% rebate.
  • 14 workshop adjacency bonuses is nearly the maximum with 98% [1].
    • In Enemy Within, the bonus is 10% each, so 6 workshops (plus the Foundry and Mec Lab) in a single block can reach the 99% rebate maximum.
  • To win the war on XCOM's ever-limited budget, a collection of Workshops is a sound investment. The reduction of materials and cost to build items saves resources (plus the savings from having more Engineers) to build Satellite Uplinks/Nexus and satellites, which in turn gets you more credits per month.

The Foundry

The Foundry is one of two places you can research equipment upgrades.

Build Facilities

Non-unique facilities require more manpower as more of the same are built. This increase does not apply to the power facilities. After researching Advanced Construction in the Foundry it is possible to build facilities in rush mode. It requires twice as much of money, Elerium and Alloys but shortens time by 50%. Unlike everything else that can be produced in Engineering, the price and item requirements do not lower based on how many Engineers you have.
