History YMMV / HeavyWeapon

** [[KillSat Romanov Attack Satellites]] will fire an [[OneHitKill instant-death]] laser below them, you have to push them backwards so they don't move towards you while firing the beam.

* ScrappyMechanic: 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 PS3 and Xbox360 ports, with an analog stick for movement and the other for aiming/shooting.

* ThatOneLevel: Several levels contain That One Wave, often GoddamnedBats paired with DemonicSpiders (or even two or more DemonicSpiders paired up together): Examples are Satellites/Atomic Bombers paired with Blimps or Bulldozers, or Tanks/[=ICBMs=] paired with Bulldozers.

** Mechworm. Touching this dude is an instant death, and when its health gets low, it gains the ability to pop up under you. On the second fight, it pops out of the ground ''much'' faster, and if you don't move as soon as you see the {{Wormsign}}, you die almost immediately.

** Mechworm on the second fight. When his health gets low, it gains the ability to pop up under you. On the second fight, he pops out of the ground ''much'' faster, and if you don't move as soon as you see the {{Wormsign}}, you die almost immediately.

* UnfortunateImplications: The reason why the UpdatedRerelease had the level names as well as some of the boss names changed, as the names reflected either war-torn countries or Communism.

* DemonicSpiders: Havanski Atomic Bombers, they drop a large bomb that can not only take a lot of hits, but will ''[[OneHitKill instantly kill you]]'' (and your [[TotalPartyKill whole party]], in War Party Survival) if it hits ''{{a|lwaysAccurateAttack}}nywhere'' on 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).

* DemonicSpiders: Havanski Atomic Bombers, they drop a large bomb that can not only take a lot of hits, but will ''[[OneHitKill instantly kill you]]'' (and your [[TotalPartyKill whole party]], in War Party Survival) if it hits ''[[AlwaysAccurateAttack anywhere]]'' on 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).

* ItsTheSameSoItSucks: 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.
* MostAnnoyingSound: "[[AvertedTrope CEASE]] [[FriendlyFireproof FIRE]]!!!"

* MostWonderfulSound: '''"MEGALASER!!!"''' Cue Ass Kicking via OneHitKill WaveMotionGun...

* ThatOneBoss: Eyebot. It's bad enough that it comes at the end of the level that introduces the infamous [[DemonicSpiders Havanski Atomic Bombers]]. Then it just eats up your few remaining lives with its [[OneHitKill massive lightning blasts that kill you in one hit]].

** Fovraski Cruise Missiles. These fly in quickly, then do a 90-degree turn and head straight down when they go over a player. They are ''extremely fast'', which means that you'll probably be forced to move left/right to avoid these guys or aim directly upwards to destroy them.

** Barskov Munitions Blimps. They're big, tank damage for other enemies, and then there's the fact that they blow up into a random shower of indestructible[[note]]Unless you have the Nuke/Megalaser[[/note]] shots when killed and the shower may be impossible to avoid depending on the spacing between the shots. Thankful;y there's ''usually'' a gap in the shower.

* CrowningMusicOfAwesome: It may be ''very'' repetitive, but the [[http://www.youtube.com/watch?v=ZiBjqXpBNnw level music]] (used for all missions) is actually pretty good.

* BreatherBoss: War Wrecker in stage 4. If you know how to avoid the OneHitKill wrecking ball, it should be a breeze. It comes between the rather annoying War Blimp and the tough [[ThatOneBoss Kommie Kong/Gorillazilla.]]

* UnfortunateImplications: Probably the reason why the UpdatedRerelease had the level names as well as some of the boss names changed, as the names reflected either war-torn countries or Communism.

* DemonicSpiders: Havanski Atomic Bombers, they drop a large bomb that can not only take a lot of hits, but will ''[[OneHitKill instantly kill you]]'' if it hits ''[[AlwaysAccurateAttack anywhere]]'' on 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).

** '''Anything''' can be this, depending on the enemy combinations you might fight in a wave.
