I got a chance to go hands on with Ryse today. Unfortunately there was no campaign and we could only play the co-op multiplayer. You go as a pair (or they paired you up) and you get to play the co-op gladiator missions. The good news is there is absolutely no QTE. When you are fighting well and getting your strikes, the skull icon appears for an execution. At this point you can choose to feel epic and press B for an execution bonus move or simply ignore it. Obviously you want to execute as it spurs up the crowd and your XP. The combat is engaging and the enemies are no pacifists, it can actually get hard and they will surround you. I also soon found out don't go "Rambo", you will be quickly surrounded and die. You will do better if you play as a team with your buddy and watch each others backs.
The moves are simple - weapon attack, hard weapon attack, shield attack and hard shield attack and defence. You also have your god powers and can pickup and throw spears (or use stationary weapons). Don't expect a street fighter level button combos. This is not how the game is meant to be played. The game is not a 1 vs 1 combat but 1 vs many. You don't have time pulling off fancy button combos on one enemy. When I concentrated on one guy I usually got engulfed. The combat is about managing the multiple enemies who are attacking you. Its about how well you time your strikes and defend. For example, I heavy strike the enemy in the front, defend the rear, a shield strike at the flanks back to guy in front e.t.c and you build up for the executions. If you do it right you will have multiple executions that will make you feel like a Boss.
Now for the bad, I can't speak for the campaign but the multi-player did feel a bit "clunky" and some visual downgrade (compared to SP). I don't know why the disparity between the campaign and mp (SP looked more demanding), perhaps they are done by different teams? I hope they polish it so that the cross over from playing the single player to multi-player is not "disconnected". I also found the visual cues needs improving, sometimes its not completely obvious what you have to do. In any case I am interested in this game and if they polish up the MP it would be a blast "horde like" experience to play with your friends. As very little is known about the SP, I hope it will have a very engaging story and they are keeping it tightly wrapped.
