We present the investigation of strong bare-coupling regime SU(2) lattice gauge theory with 8 fermion flavors in fundamental representation. The simulations are performed unimproved staggered fermions and plaquette action. One bulk phase transition is observed through measurement plaquette. results cold-start hot-start simulations, as well hysteresis study, indicate order this can be weakly first order. Using smeared Polyakov loops, a method inspired by constraint effective potential, we study vacuum structure near confining-deconfining transition. Dirac operator eigenvalue spectrum investigated, where further analysis needed to clarify properties chiral structure.
