These chips are gone forever once you use them. All chips dropped by enemies seem to be in this category. You can have multiple instances of these chips in your inventory, and when you equip one, it will automatically deduct chips from your inventory each use so long as you have any instances remaining.
Attack+
Increases your damage for a limited time. Dropped by certain large enemies and “spellcasters.”
Cannon
The various Cannon-class chips (Cannon, Hi-Cannon, MegaCannon) fire a projectile straight forward. Dropped by Canodumb-type enemies and other shooters.
Earthquake
Drops an Earthquake virus on an enemy. Dropped by those very-same enemies.
Invisible
Makes you invulnerable to enemies, shots, and spikes for a limited time. It appears you can use an Invisible and then equip a different chip in its slot with no ill effects. Sometimes, but rarely, dropped by the ghost viruses.
MiniBomb
These various types of bomb chips (MiniBomb, SmallBomb, BigBomb, CrossBomb) lob a bomb starting in a diagonally-upwards trajectory.
Recovery
Restores your HP by the listed percentage. Dropped by a variety of enemies, including the same ghosts that give you Invisible chips.
Shockwave
This typical Mettaur chip emits a blast along the ground. As with most chips, this has variations: Shockwave, Sonicwave, Dynawave.
When used, these chips change your primary weapon (normally your Buster). The icon in the upper-left corner will darken to show that it’s in use. Press the corresponding button again to switch back to your Buster. These chips can be used and equipped infinitely, but you only ever see one in your inventory even if you collect the chip multiple times.
DashAttack
Dash-type chips cause you to shoulder-dash half a screen in the direction you’re facing, damaging whatever you pass through, usually without taking damage yourself. The dash cannot be canceled once activated. If used in midair, it resets your falling speed to zero at the start of the dash, but gravity proceeds as normal throughout the dash (so it’s not quite as useful as the
X series air dash, but can still get you over enemies).
GutsPunch
The punch-type attacks throw a giant fist in front of you, and moves you forward a few pixels. Cannot be used in midair.
Sword
The various sword chips slash an arc in front of you. WideSword extends the top and bottom of the arc; LongSword makes the arc reach a little further; and the elemental swords have their corresponding elements.
These chips are displayed darkened as soon as they’re equipped. They provide some continuous enhancement. As with the toggles, you only ever have one in your inventory even if you collect the chip multiple times, but they can be equipped and unequipped infinitely without disappearing.
AirShoes
These let you jump a little higher. Some platforms are positioned such that you can just barely reach them with AirShoes but just barely not without. These shoes also make you jump a little more aggressively, so beware equipping them in areas with spikes overhead, or where small jumps are paramount.
AreaSteal
A creative interpretation of the classic Battle Network chip. This chip lets you run and climb ladders faster. You can pretty much run over 1-block gaps normally, but with AreaSteal it’s a given, and the boost stacks with other speed-ups as well.
Undershirt
Undershirt provides a substantial armor boost, making even Site Style playable with relative ease, and WoodShield able to stand up to repeated abuse form the DreamVirus’s worst attacks.
