the unlock tree is decent, you grind cash to buy up weapons, vehicles and base upgrades and theres a fair list to work through. but once youve maxed your arsenal the loop is just raid other bases and rebuild, over and over. theres no real endgame ladder or completion reward beyond having the strongest stuff. fine for a tycoon combat hybrid but it runs out of long term goals fast. i maxed the main unlocks in a couple sessions and there wasnt much left to chase.
