XCOM Database[]

The Genetics Lab enables genetic modification of XCOM soldiers. Soldiers who receive genetic modification retain both their class and rank. Only one Genetics Lab may be constructed, although it counts as a Laboratory if built next to one. Dr. Vahlen recommends that XCOM deploy genetically enhanced soldiers as soon as possible.
