If you're a fan of sneaky-stabby games, but just aren't sure if Dishonored 2 is something you will enjoy, I am glad to say that I bring some good news! According to Bethesda's most recent announcement Dishonored 2 will be getting a free trial on all platforms starting from April 6th.
You will be able to play through the first three missions of the campaign as either Emily or Corvo, and with absolutely no time limits it should be more than enough to give you a good idea of what Dishonored 2 is all about. And best of all, one of the missions you'll be able to play is actually pretty damn awesome, so don't worry about this just being some sort of tutorial nonsense.
Once it becomes available you can download the free trial by heading over to either Steam, the PSN Store, or Xbox Marketplace. Naturally, your progress throughout the free demo will be saved, so if you ever decide to purchase Dishonored 2 you will be able to continue from where you left off.
As a final note, allow me to share with you one of the pre-launch gameplay previews that showcases a short and sneaky trip through the Clockwork Mansion. It won't spoil the entire zone for you, but it will give you a brief overview of what to expect from Dishonored 2's stealth system. Enjoy!
