The premise of this game is that you fly a World War II era plane through various unrealistic combat scenarios and blow up pretty much everything that comes up on screen. The whole thing is presented in a top-down view, just like the original game. You can also pick up weapon upgrades that will change your weapon fire to spread guns, lasers, and more. The weapons in this reminded me a lot of the classic NES game called Contra. At the end of each level you will have to fight a boss of some kind, and those boss battles are extremely difficult.
This is a very busy game in that your screen will always be full of enemy tanks and planes, and they are constantly shooting back at you. Much like the original, there is sort of a formula to the way the enemy planes move. Unless you have Spiderman-like reflexes, your best bet is to play through the levels a few times until you know what to expect. When it comes to the boss battles, there is generally one main strategy for how to defeat them, and this usually involves exploiting a weakness of some kind. You also need to figure out the rhythm of their weapons in order to dodge bullets.
