As a gamer with a long carreer of games, I am really looking forward to test this demo because I'm a real big fan of the first 2 crysis so I searched for some multiplayer gameplays and previews and found out that some people say that the controls aren't great.
I searched further and found videos of people playing but having a tremandous hard time killing the enemy (Maybe it's just them having no skill). So, I can't confirm that right now because I haven't tried it yet but after my play test of tomorow, I'll come back to post and share my thoughts.
here are the links of the ''supposed bad players'':
