It has a tutorial, and as bare-bones as it is its very existence makes the PS2 NPE better than DUST's. There is also the VR room where you can test everything in the game, and the trial feature to test something in heated combat.

Seeing as you only played for a day I'll cut you some slack, but if you ever fired at a forcefield, you were doing it wrong. And if MAXes were your main problem and they slaughtered your tanks, you and your armor were both doing it wrong. A MAX will die to a single well placed C4, and will die almost instantly if he is alone against a squad. They are huge and nigh impossible to miss, and can be heard clomping up on you from 50 meters plus. They also only have CQC weapons; NC with a shotgun, TR with a chaingun, and VS with a laser LMG.

Also, it is physically impossible for a MAX to take anything, let alone a whole base. They cannot capture points, cannot hack terminals, cannot sabotage generators, and cannot drive vehicles. They also cannot function alone because they have paltry ammo reserves and no HP regeneration, as well as moving at a snail's pace between buildings. They can't even do anything while sprinting/coming out of sprint because they count as a vehicle and have to fully decelerate to walking speed in order to fire their guns.

Not trying to say you suck at FPSs, but if you had such problems with MAXs you probably just plain suck at PS2
