Bosses in video games are meant to test you to the extreme, being a massive step up from the usual enemies you encounter both in power and importance. And, not surprisingly, fighting these baddies the traditional way is normally a damn painful experience.
Is there anyone who'd honestly say no to a sneaky little way of gaining the upper hand?
With items that are either hard to find, require an enormous grind to obtain, or just plain don't make any sense to use in battle, you can often end up trivialising an opponent who would usually have thrown you about like a ragdoll for hours on end.
Some might say this takes away the fun of squaring up against something you'd have no chance of killing in real life. You might also think it's... cheating a little bit. But wherever you stand on this, after being trounced over and over again by the same unbeatable boss, there's no greater satisfaction than pulling out your A-weapon and watching that once fearsome enemy turn to putty in your hands.
In some ways, it's a shame you can't use these items to breeze through the WHOLE game.
10. Chairman Drek - Ratchet & Clank (2002)
Chairman Drek is the main antagonist of 2002's Ratchet & Clank, and, as the final boss, he fights you in a heavily weaponised hovering mech suit. In a series as chaotic and trigger-happy as Ratchet & Clank, you'd expect the final boss to not exactly be a walk in the park. And it isn't.
With multiple stages set across a number of crumbling terrains - not to mention that ammo doesn't grow on trees - fighting this boss is quite the challenge indeed. Unless, of course, you've gone the extra mile to fork out for the coveted RYNO, which makes Drek go down in less than half the time.
Aptly named the Rip You a New One, the RYNO is dangled in front of your face early in the game by a shady dealer. It'll tempt you instantly, but when you see that the weapon costs 150,000 bolts to buy, your smile will soon disappear.
You've got to really want this gun to be able to afford it on your first playthrough, foregoing pretty much every other purchase just to limit the insane money grind you'll have to do.
It's definitely worth it, though, as the rapid fire rockets that spew out of the RYNO make mincemeat of literally everything you come up against. With this in your arsenal, Drek basically needn't have bothered showing up.
