-----------------
|
||||
- 3-01 Weapons -
|
||||
-----------------
|
||||
|
||||
- Polar Star
|
||||
You find this weapon at the very beginning of the game. It's not the strongest
|
||||
weapon, but it's definitely one of the easiest to use and useful in a wide
|
||||
variety of situations. Keep it when Curly asks you to trade in the Sand Zone
|
||||
if you want the Snake or Spur weapons later.
|
||||
|
||||
- Machine Gun
|
||||
Given to you by Curly Brace if you trade her the Polar Star. Keep the Polar
|
||||
Star when she asks you by choosing "No" if you want the Snake or Spur later in
|
||||
the game. The Machine Gun is still an excellent weapon, though, and perfect
|
||||
for your first time through the game as it's not only the easiest Polar Star
|
||||
trade-off weapon to obtain but Level 3 allows you to float upwards in the
|
||||
air as long as you have ammo, vastly increasing your mobility. It has an ammo
|
||||
count of 100 but auto-recharges, and the recharge rate vastly skyrockets once
|
||||
you get the Turbocharge key item which only works with the Machine Gun.
|
||||
|
||||
- Snake
|
||||
Obtained by keeping the Polar Star when Curly asks you to trade and then giving
|
||||
both the Polar Star and Fireball weapons to Chaba (the Gaudi shopkeep in the
|
||||
Labyrinth) when you reach him. It's unique in that it's the only weapon in the
|
||||
game capable of passing through walls. It's very similar to the Wave Beam in
|
||||
early Metroid games.
|
||||
|
||||
- Spur
|
||||
Unique weapon considered by many to be the ultimate weapon in the game, and it
|
||||
probably should be considering how long you have to keep the Polar Star if you
|
||||
want this. You'll need to get the Booster 2.0 and fly back into the very first
|
||||
area of the game--before the Mimiga Village--and revisit the hermit weaponsmith
|
||||
with your original Polar Star to earn the Spur. Instead of levelling up
|
||||
through crystals, it "gains levels" the longer you keep the shot button held
|
||||
down, and is the only weapon that has a different effect at MAX level compared
|
||||
to Level 3.
|
||||
|
||||
- Missile Launcher
|
||||
You recieve this early in the game, in the Egg Corridor. It's the only weapon
|
||||
with limited ammo that doesn't automatically replenish, but it's also very
|
||||
powerful. Easy to use, mostly works like a longer-ranged and more powerful
|
||||
version of the Polar Star.
|
||||
|
||||
- Super Missile Launcher
|
||||
Found in the Boulder Chamber, this is an upgrade to your Missile Launcher which
|
||||
basically makes every aspect of it better, though it takes a bit more EXP to
|
||||
level up. Besides raw damage, the most noticeable upgrade from the standard
|
||||
Missile Launcher is the velocity of the missiles, or the speed at which they
|
||||
travel across the screen. Also, the missiles launched by this weapon are gold
|
||||
in color.
|
||||
|
||||
- Fireball
|
||||
Given to you by Santa (the Mimiga with a strange name, not the Christmas guy)
|
||||
in the Bushlands for helping him get back into his house. This can be a decent
|
||||
alternative to the Polar Star or Machine Gun early in the game, as it's the
|
||||
only weapon other than the Polar Star you'll find with truly unlimited ammo for
|
||||
awhile. It shoots balls of plasma that bounce around along the ground, great
|
||||
for grounded enemies and for use around slopes, and its rapidity mixed with its
|
||||
good power for its point in the game makes it good against many bosses.
|
||||
|
||||
- Bubbline (aka Bubbler)
|
||||
A very unique hidden weapon obtainable by taking a Jelly Juice jar back to the
|
||||
assembly hall in Mimiga Village and putting out the fireplace there. It's
|
||||
called the Bubbler in the English fan-translation of the PC version of Cave
|
||||
Story. It has a lot of potential use at Level 3 but is otherwise pretty under-
|
||||
whelming. It has an ammo supply of 100 which regenerates on its own slowly.
|
||||
|
||||
- Blade
|
||||
Very powerful weapon given to you by King at a certain point in the story. Its
|
||||
rapidity is very low (except for rapid releases of Level 1 or 2 shots in a
|
||||
strong enemy or boss's face) and it has a short range, but the damage is huge
|
||||
and it has infinite ammo.
|
||||
|
||||
- Nemesis
|
||||
Special weapon of great strength that can be obtained by trading King's Blade
|
||||
to Mister Little. The weapon is unique in that levelling it up outright causes
|
||||
it to weaken in every possible way, and it only takes 1 exp to level it up both
|
||||
levels. Luckily, this also means that taking a hit from just about anything
|
||||
will guarantee resetting it to Level 1, at which point it's at its strongest.
|
||||
Overall, it's probably a more similar weapon to the Polar Star than anything
|
||||
else, even the weapons that you actually trade the Polar Star for. Infinite
|
||||
ammo.
