Where is the csol2 hide-and-seek mode?

Can be turned into a hidden mode of various props. Every round, a random number of players join the TR camp, become props and integrate into the environment, and ensure that they will not be discovered within the specified time. Click the right mouse button to lock the current position, and click the Q key to open the free view.

The remaining players automatically join the CT camp. In order to find and destroy the props transferred from TR camp within the specified time, attacking the correct enemy HP will increase, but shooting the wrong target will cause HP to decrease as a punishment. At the end of each round, the CT camp will move faster without HP's punishment.
