[Update] Unfortunately the video has been taken down, so we replaced it with another one featuring a similar walkthrough of the first mission, courtesy of OneCokePlz, which can be viewed below. It's only the first part of the walkthrough so not too many spoilers present for those of you willing to check it out.

MiastoGier TV has released a video showcasing the first 40 minutes of Assassin's Creed Syndicate. The footage which can be viewed below, obviously contains some minor spoilers, although it does attract interest for more as it seems rather interesting. As usual, the adventure begins with Abstergo, which hopefully will feature some modern-day segments, as many fans have been asking for more, and continues with Jacob Frye in London 1886, followed by some gameplay featuring his twin sister Evie.
