I got this today along with Bionic Commando (it was a 2 in 1 bundle, so...) and it's kinda fun.  I had never heard of the game until I saw it in the auction.  It's reminiscent of Guerilla War, which makes sense because it's by SNK.

The only quirk so far is the controls of aiming the tank's gun.  That, and needing to press start to clear a message.

The game sure blows you up when you die though.  I'd check it out if you got it lying around.

My friend had this game when we were kids. It is very fun. I like running the soldiers over lol. It's cool how you get different types of ammo and get to choose which power ups to use. If you have never played it, you should check it out.
