The strong interactions program of NA61/SHINE, a fixed-target experiment at the CERN SPS, focuses on the search for the critical point of strongly interacting matter. The strategy of the Collaboration is to perform a comprehensive two dimensional scan of the phase diagram $\mu_{B} – T$ by changing the collision energy and the system size. If in this scenario, the system freeze-out occurs in the vicinity of the possible critical point, then a region of enhanced fluctuations is expected in suitable fluctuation measures. 

The talk will review the ongoing NA61/SHINE analysis on multiplicity and transverse momentum fluctuations in terms of intensive and strongly intensive quantities. Furthermore, their pseudorapidity dependence, which corresponds to a scan in the baryon chemical potential $\mu_{B}$ at the freeze-out stage, will be presented along with the study of the higher moments of multiplicity distributions.

The talk also discusses the approaches to corrections of the results and possible systematic problems in the analysis.
