Heavy Weapon/YMMV


 * Breather Boss: War Wrecker in stage 4. If you know how to avoid the One-Hit Kill wrecking ball, it should be a breeze. It comes between the rather annoying War Blimp and the tough Kommie Kong/Gorillazilla.
 * Not so much when you have to re-fight it, though, as it now kicks up rocks from the ground which are not very easy to destroy in time.
 * Crowning Music of Awesome: It may be very repetitive, but the level music (used for all missions) is actually pretty good.
 * Demonic Spiders: Havanski Atomic Bombers, they drop a large bomb that can not only take a lot of hits, but will instantly kill you if it hits the ground. For a large enemy, they also give you a measly 3000 points when defeated (as compared to the less deadly blimp that gives 25000).
 * Romanov Attack Satellites will fire an instant-death laser below them, you have to push them backwards so they don't move towards you while firing the beam.
 * Contact with a Shovak Bulldozer will instantly destroy you, so you have to constantly keep shooting at them to repel them back. Not very easy to do when having to kill Airborne Mooks at the same time!
 * Goddamned Bats: Most of the weaker enemies, especially Fighter planes when they are paired up with the blimps. Homing-missile helicopters are also really irritating too. Then there are ground-based Mooks like the rocket truck and the tank, both of which force you to aim downwards.
 * It's the Same, Now It Sucks: Both the level design and bosses. Each level has many different "waves", which consist of a set of enemies. Trouble is, you'll be eventually encountering the same few waves over and over again ad nauseum. And then there's the bosses. Bosses 10-18 are pretty much souped-up versions of the first 9 bosses, usually just faster and with more HP.
 * Most Annoying Sound: "CEASE FIRE!!!"
 * "QUIT IT!!!'
 * "STOP!!!"
 * "Aaaaarrrghhhh!!!"
 * Most Wonderful Sound: "MEGALASER!!!" Cue Ass Kicking via One-Hit Kill Wave Motion Gun...
 * Scrappy Mechanic: In the PC version, your tank aims with the mouse cursor, AND moves towards the mouse cursor. This makes it hard to stay in one position and attack, and even worse when you have to face against Bulldozers that kill you on contact. Fortunately, it was solved in the Play Station 3 and Xbox360 ports, with an analog stick for movement and the other for aiming/shooting.
 * Unfortunate Implications: Probably the reason why the Updated Rerelease had the level names as well as some of the boss names changed, as the names reflected either war-torn countries or Communism.
