It's been an incredible week of Counter-Strike and the huge upsets kept coming all the way through the final day.
One of the favourites missed out on the playoffs, whilst a very unlikely team managed to book themselves a spot in London.
Let's take a look at how the action went down.
Vitality haven't looked close to their best recently, but that didn't stop them from being able to secure a win over FaZe and advance straight to the semi-finals.
FaZe picked up map one, Mirage, 19-17 after some clutch CS from both teams, with standout performances from broky and frozen helping to give them the advantage.
However, FaZe couldn't capitalise on that advantage, and after a second double OT of the series was won by Vitality on Nuke, the BLAST.tv Austin Major champions managed to take the series with a conficent, 13-5 display on Inferno.
M80 have been the big surprise package of BLAST Open London thus far, and they continued their underdog run by securing the playoffs with a win over fnatic.
A heart break for the UK crowd as it means they'll miss out on seeing CYPHER play, fnatic just couldn't pull off the extra win as M80 took them down 2-0.
13-8 on Ancient and 16-14 on Train, blameF impressed on the side of fnatic, but it was Lake who was the star of the show, firing M80 into the quarter-finals with 45 kills across the two maps.
FURIA have been in incredible form recently, looking almost unstoppable as they look to continue their resurgence with molodoy and YEKINDAR.
Coming up against MOUZ in their most recent test, FURIA passed with flying colours one again, booking their place in the semi-finals with a 2-0 victory.
13-7 on Inferno and 16-14 on Mirage, FURIA dug deep on both maps, constantly winning clutches and finding openings that left MOUZ with no chance of advancing to the more favourable spot at the weekend.
Well, it looks like London won't be getting to see donk - G2 eliminated Spirit in the final match of the group stage.
An incredible result for the G2's new lineup, it took all three maps for them to get there, but the final map of the series was utter domination.
The series kicked off with a 13-11 in favour of Spirit on Mirage, but G2 managed to then keep themselves alive with a 16-13 win on Dust2 thanks to 47 combined kills from HeavyGod and malbsMd. Sent to Ancient for the decider, G2 were firing on all cylinders, and they confirmed their spot in London with a 13-1 win.
