Re: Weapon loadout: how does to work?
It depends on the class how many weapons you can carry.
As a Solder you can carry 5 different Weapons (Sniper rifle, Assault rifle, Shotgun, Pistol and a heave weapon), as an infiltrator 4, (Sniper rifle, Submachine gun, Pistol and a heavy weapon) classes who focus on powers can only carry 3 Weapons, (later in game 4 / Pistol, Submachine gun or Shotgun and a heavy weapon.)
