Otherside Entertainment outlined upcoming changes for Thick as Thieves in an Update 4 preview. The patch focuses heavily on artificial intelligence improvements, environmental destruction, and quality-of-life adjustments.

Guard Intelligence and Reactions

Guards are receiving a major intelligence upgrade in Update 4. Non-player characters will react to a wider array of environmental triggers, such as knocked-out peers nearby, shattered glass, and active car alarms, leading to heightened security consequences.

Environmental Interaction

Players will soon be able to shatter glass throughout the world. While broken glass opens up alternative routes into buildings, the noise generated will anger nearby guards. The update also introduces interactive pipes with unexpected results.

Novice Mode and Quality of Life

The match timer on Novice difficulty is being significantly increased, allowing players to spend more time exploring levels. The patch will also include a variety of general bug fixes and minor improvements.

Why this patch matters

Update 4 transforms environmental awareness in Thick as Thieves, turning glass and sound into high-stakes mechanics for stealth players.
