Investigation displays your overall progress through the campaign, including current status and completed, pending, and upcoming Operations, as well as active Dark Events, and the info on the Leader of a given group.
The Investigation process is done automatically, only requiring to wait and complete the corresponding missions. This process can be speeded up by completing special Lead Missions which have the decreasing of Investigation time as the reward. Until these Investigation Missions are complete, they will generate 1 Unrest per day at the District where they are located.
Darks Events currently underway may make your Missions more difficult. They can make enemies more powerful, more numerous, or worse.
Investigations each focus on a separate enemy Faction. They can be undertaken in any order, one at a time. Investigations contain three types of activities: Groundwork, Operations, and Takedowns.
Groundwork is a special type of Tactical Mission that introduces an Investigation’s major conflict. Each Investigation starts with one Groundwork Mission that must be completed before the Investigation can progress.
A series of Operations forms the bulk of an Investigation. Each Operation has a Hidden Target, an end goal that must be unlocked by completing different actions. These actions, called Lead Missions (purple), and Situations (blue) are what progresses the game.
- Lead Missions (purple) unlock the Hidden Target sooner and provide rewards.
- Side Missions (yellow) don’t advance the Operation but provide important resources and equipment to keep the squad prepared for danger.
- Situations (blue) can be completed from within HQ. They don’t require combat and cost nothing but time. They advance progress towards the Hidden Target.
- Hidden Target Missions (purple) are operational end goals only available after a certain number of Lead Missions and Situations have been resolved (they can't be completed immediately, require few days of waiting). Completing a Hidden Target Mission marks the end of an Operation.
Takedown marks the end of each Investigation. These dangerous and challenging combat Missions neutralize the corresponding enemy Faction by confronting its powerful Leader. This mission always has three Encounters in total. You may encounter a mini-boss in one of the early phases. The main boss appears in the third encounter. Like Groundwork Missions, there is only one Takedown per Investigation.
Time is a critical consideration in XCOM: Chimera Squad.
- In-game time typically advances by completing Missions.
- Many Strategy tasks take a certain number of in-game days to complete.
- Missions are only available for a limited time.
An agent assigned to a strategy task (in Assembly, Spec Ops or Training) that takes two in-game days to complete will not be available to deploy on Tactical Missions until those two days have passed. Agent can be removed from facility slots, but at the cost of progress. You can sometimes manually advance the in-game day without completing a Mission. However, this can trigger Unrest to rise in some parts of the city.
