It was a nail-biter series, but Natus Vincere proved the victor over Tempo Storm and they move on to the semifinals of the IEM Season X World Championship Katowice.

The series opened up with Overpass, a map that Na`Vi were expected to dominate on. TS put up a stronger fight than expected, but it was Na`Vi's map to lose and they didn't crack under pressure, taking the map 16-10.

The second map was Cobble and saw lucas1 set the tone for the map, getting a sick 4K in the second round.

TS continued to have an incredibly strong T-side and entered the second half with a 13-3 score. However, Na`Vi came back on their T-side and forced an overtime. Unfortunately, they lost all momentum and TS ended the map 19-15.

The deciding map of the series was Mirage, a map that Na`Vi weren't particularly strong on, but it was yet another close series. TS started off with a solid CT-side, ending the half at 10-5, but they couldn't hold onto their momentum on the T-Side. TS won 13 rounds, but then Na`Vi rolled eight rounds in a row to take the map and the series.

Natus Vincere move on to the semifinals to face Luminosity Gaming, while Tempo Storm are eliminated and place in Top 6.
