Sebastian "SzajnA" Krzemień is Polish terran player.
Sebastian SzajnA Krzemień is a former member of the Polish National Team before the StarCraft II Beta, but never achieved any notable finishes in major tournaments.
After the Beta Szajna appeared in several smaller tournaments like the second A/B Ranking tournament on ICCup. During this small tournament the Polish Terran gained somewhat of a reputation after beating a number of high class foreigners with silly strategies using the smurf "BEAMFACE". His only entry in bigger tournament was for the AoV iCCup StarLeague, where he could qualify with a B Rank, defeated spx and Pike in the group stages and eventually lost to Scan in the Quarterfinals.
