Yes. You basically get experience points and advance in levels gaining certification points. You then use these certs to 'learn' new skills such as hacking (to gain outposts and bases) or how to drive a tank, or quad or fighter or the troop carriers (airborne and GVs). You can even get a stealth suit that makes you invisible!
It's quite well balanced and there is always a need for different types of player to work together - such as pilot, grunt or powered armour (MAX) soldier. Engineers, hackers and medics are also required.
It's fun and frenetic and not very deep - ideal for light relief.
