  • In XCOM: Enemy Within, the hidden +20 Aim bonus has been removed.
  • Smoke enhanced by Combat Drugs is easily identified by the white powder within the effect area.
  • The will bonus granted by combat drugs does in fact register against psionic attacks(at the very least mind control). Although it may not show it.
