Near-criticality is achieved in strongly interacting matter in two different ways. The Large Hadron Collider (LHC) produces quark gluon plasma (QGP) at vanishing net density, which is sensitive to the nearby O(4) criticality of the chiral limit. The Relativistic Heavy Ion Collider (RHIC) is scanning the intermediate densities towards the Z(2) critical end-point in the temperature-chemical potential phase diagram. The collisions in the future FAIR facility at GSI-Darmstadt might probe the same $Z(2)$ end-point from the first order side of the transition line. This is one of the main goals of this Germany-based, multi-billion Euro project. In this project we calculate high order electric charge fluctuations, highly sensitive measure of deconfinement, also accessible to measurement, the equation of state for simultaneously non-zero baryon, strangeness and electric charge density, and analytical estimators for the Z(2) critical end-point's location to be found by the CBM at FAIR.
