I don’t mind difficult games, but I like ones that offer rewarding experiences and noticeable upgrades once the learning curve is complete. Battlezone does little to reward players and the various waves of enemies become tiring rather quickly. The foundation here is solid for a fun game, but the implementation falls short and doesn’t allow much room for the game to be enjoyable for any length of time. Perhaps some tweaks to the randomized challenge spikes can be patched in, but for now it’s a game specifically targeting only the hardest of the hardcore who value unfair challenge above all else.
