It's clear how the Viking raids in Assassin's Creed Valhalla are supposed to work. Ubisoft's latest historical adventure has you playing as a brave Norse warrior rampaging across England with your fellow raiders, battling Saxon soldiers and ransacking their burning cities. That's not how I play. I discovered early on that, instead of approaching an enemy site in my longship, with all my skilled courageous troops, then engaging in open, bloody warfare, I had more success if I went ahead alone and hid in the bushes, picking the guards off one by one and quietly hiding their bodies. You can clear out a whole town without a scratch, and then your fearsome warriors can pop in at the end and help you open the treasure chests.
