History YMMV / HeavyWeapon

** S-34 Reflex Fighters. They fire homing missiles like the two helicopters but luckily leave the screen. What makes them annoying is their [[DeflectorShields deflector shields]] that sprays unlikable plasma shots in random directions every time your [[SpreadShot spread shot]] regular bullets hits their shields. Thankfully, their shields are useless against your special weapons.

* PortingDisaster: While the [=PS2=] version is far from a terrible game and separates the aiming and moving controls like the earlier well-done Xbox 360 version, as well as including a brand new arranged soundtrack, the aiming controls when shooting diagonally are too sensitive, which can cause you to miss various enemies. This version also lacks the exclusive content from the Xbox 360 version. Averted with the Playstation Network version, which uses the Xbox 360 version as a base.

* ItsTheSameNowItSucks:
** 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 nauseam. 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.
** People who liked the music from the Playstation versions were not happy that the Xbox 360 version simply uses the music from the PC version.

* ScrappyMechanic: In the PC version, your tank aims with the mouse cursor, AND moves towards the mouse cursor's horizontal coordinates. 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 UsefulNotes/{{PS3}} and UsefulNotes/XBox360 ports, with an analog stick for movement and the other for aiming/shooting.

** The [[https://www.youtube.com/watch?v=fII12YWEcQM title screen/opening introduction music]] for the PC version is a short yet awesome rock and roll piece with some over-the-top narration and vocals.

** Both versions of the homing missile firing helicopters (Grakin and Mokum Assualt Helicopters) will fire homing missiles often, and worse still, do not leave the screen until killed, when the boss arrives, or they manage to kill you. They also do have a good amount of health.

** 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. Thankfully there's ''usually'' a gap in the shower.[[note]]Or maybe not. If you really unlucky there might not even be one and the shots can sneak through your defense orbs.[[/note]]

** Czerk Light Helicopters. Unlike the two assault helicopters, this one shoots energy orbs at you and have the tendency to corner you in large numbers, making them irritating to defeat or maneuver. And they ''always'' come in combinations with the Grakin and Mokum assault helicopters, making all three of them a pain in the butt to deal with.

** Modified Pickup Trucks and Linstrad Tanks force the player to aim downwards. The former has slow destructible missiles, while the latter has more HP and attacks with indestructible plasma shots.

** Fovraski Cruise Missiles. They're fast, ''extremely fast'', then do a 90-degree turn and head straight down at you if they manage to go over the player. This means that you'll probably be forced to move left/right to avoid these guys or aim directly upwards to destroy them in your crossfire. And they ''always'' come in combination with Tachrok Ballistic Missiles, which limits your room to dodge.

** Another enemy that appears alongside the Tachrok Ballistic Missiles is the Palinskat Ground Attack Fighter. They operate similar to Fovraski Cruise Missiles, but instead of dive-bombing you, they dive down diagonally and shoot a few energy orbs at you.

** 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]]. The only saving grace is that its tentacles that shoot the beams are destructible.

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

** Havanski Atomic Bombers are very durable huge planes that drop a [[NukeEm 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).

* DifficultySpike: Several. The first occurs in Zamblamia, where you face off against very annoying [[MacrossMissileMassacre Mokum Assault Helicopters]], and the [[ActionBomb Barskov Munitions Blimps]], with [[WakeUpCallBoss Kommie Kong]] at the end. The next level Tankylvania provides yet another one, with the [[DeflectorShields Reflex Fighters]], and the first appearance of the ''[[DemonicSpiders extremely deadly]]'' [[NukeEm Havanski Atomic Bomber]]. Finally, the ninth level Killingrad introduces two more DemonicSpiders, the [[KillSat Romanov attack satellite]] and the [[AdvancingBossOfDoom Shovak Bulldozer]], and also contains all of the above mentioned enemies!

** Fovraski Cruise Missiles. These fly in quickly, then do a 90-degree turn and head straight down when they go over the 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.

* GoddamnedBoss: X-Bot may not be the toughest boss in the game, but he is the most frustrating one in the game, where you are forced to move left and right to avoid his One-Hit Kill Crushing attack. In the PC version, because your tank moves with your cursor, this makes it really frustrating to aim at him while moving around, and if you're really unlucky, this boss can corner you and crush you into oblivion. Not to mention, when you destroy both of his arms that block the way, you'll have to condone dodging his eyebeams, which are not a One-Hit Kill but serves as a distraction and can screw the player badly.

** 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]]. The only saving grace is that its tentacles that shoot the beams are destructible.
** Mechworm. Unlike Eyebot whose insta-kill lightning tentacles are destructible, there's no way to greatly ease the difficulty for this one. Touching this dude anywhere is an instant death, the shower of rocks and the bombs its segments drop make it tricky to safely move under its arc (especially in the PC version where you move along with your cursor). Try to destroy all the segments on its body that drop bombs? [[DigAttack it will gain the ability to pop up under you]] and causes the worm to spam homing missiles. On the second fight, it's much longer, the arc it makes is narrower (giving you less safe room), It starts popping up under you much earlier and pops out of the ground ''much'' faster, and if you don't move as soon as you see the {{Wormsign}} under you, you die almost immediately.

** Bustczar/Head Zeppelin is another example. ALL its attacks are destructible and cannot land a OneHitKill, and if you're good, it'll probably be able to use its carpet bomb attack only once. It's a breather because the previous two bosses and the next two bosses have OneHitKill moves.

** Both versions of the homing missile attack helicopters (Grakin and Mokum Assualt Helicopters) will fire homing missiles often, and worse still, do not leave the screen until killed, when the boss arrives, or they successfully kill you. They also do have a good amount of health.
