I had the pleasure of actually playing through this icy submarine stage, and let me just say it is a total trip! Not only does the large cannon in the background randomly blast away, but the smaller gun stations can be commandeered by players to blasts opposing fighters (other vehicles including a tank and airplane will also be controllable in other stages). If being in the all the crossfire isn't enough action for you, the two submarines (only one is featured in this screenshot) which makes up the actual platforms of the stage will constantly dive and rise in and out the water—leaving players swimming for dear life. If that's still not enough for you, there are also frequent collisions with icebergs! There's just so much going on and so many dynamic elements that I couldn't believe my eyes as I was playing. Power Stone is surprising, because unlike so many other games, it doesn't just deliver, but it delivers so much!
