In the 1960s Prague was the capitol city of communist controlled Czechoslovakia.
After passing Volkov's test near Kalkara, John Jack was gearing up in Prague before infiltrating a secret military facility ran by the Czechoslovakian Army in the northern part of the country. H.A.R.M. discovered that Danger Danger was up to something at this facility and they wanted to know what was going on. Cate Archer was spotted just outside of the secret military facility.
At the start of No One Lives Forever 2: A Spy in H.A.R.M.'s Way, while Cate Archer was on assignment in Japan, UNITY had sent Bruno Lawrie on a mission to Prague. Bruno was supposed to meet up with Cate later, but "Things got messy in Prague." He later caught up with Cate while she was recovering at UNITY Headquarters.
- It is not known if Bruno's mission mentioned in NOLF2 had anything to do with the events of Contract J.A.C.K., however Archer was just outside the facility being infiltrated by Jack. Archer could have also been investigating the encoded messages from Danger Danger and Bruno could have followed up on the mission after Archer was sent to Japan.
