The game is quite dynamic and very demanding of the player. There are levels, but they do not carry any payload. Don't expect your health to increase or your damage to grow. Levels simply show how long you've been playing and how experienced you are, not your character. Maximum - new types of weapons will be unlocked. But new ones do not mean better than old ones. Each weapon has its own weight, length, and type of warhead; you really need to learn how to use each one. A light infantryman with a short sword or knife can chop a heavy vanguard into mince if he is not agile enough.
