The concept is interesting and offered a good value for replayability. The art style and level of world building is fantastic.
The game wants you to use different combinations of powers and gun play to tackle assassinations. you can be stealthy if you want or go guns blazing.

Issues with AI being too dumb as present but they can easily take you out with their numbers.

Definitely fun for any fan of Arkane's other projects.

Multiplayer is fun, very similar to Watchdogs or Dark Soul's invasion mechanic but I don't think a player base will stick around for long post release.
