Assassin's Creed Syndicate still has a lot of secrets to be discovered, being out in the wild only since a few hours – at least officially. One of the most juicy is the chance to play an entire section in World War I with a completely new female protagonist called Lydia Frye.
She is Jacob's Granddaughter, as experienced Assassin trained in the Brotherhood with the full skill tree of perks unlocked. You can “grab” her the way we explain you below and play a few missions around Tower Bridge area in London. In order to play with Lydia Frye, you will have to reach the Sequence 6 after approximately 15 hours of playtime. Go on the right edge of the map in the Thames district and find the fast travel Portal to WW1 hidden in the center of the river.
WW1 is a mini sandbox with many missions like shooting down enemy aircrafts or liberation side missions, which you will be able to play as an entirely new, not promoted character called Lydia. It is interesting to note Unity also included a World War II sequence, so the link to modern wars is getting increasingly important in the economy of the series, it seems.
