Hello man! I am glad you liked my game, and that you liked the 1st person mode. Indeed, for closed environment, indoor maps, 1st person is the best way to go! As for more open maps, 3rd person view gives you a better field of view. Yeah, there will be 3 modes. Campaign, Multiplayer and Challenges. This mode challenges is similar to what you want, just run and gun, however, trying things like perform the maximum number of headshots, killing all enemies with just a knife, using a sniper, using just a molotov, survive enemies waves using just a pistol (makarov), and so on.
