Tachyon Phase

The Tachyon Phase is a playable character class (codenamed by LEAF-Prime as an "IR Phaser") in Plants vs. Zombies: Infinite Generation. In general, Tachyon Phase users tend to have high Defense, low Mobility, and middling Regeneration. Armor drops for this class reflect this by weighting stat rolls for these attributes in a similar manner, unless forced to do otherwise.

Overview
Tachyon Phase users have their frames equipped with thick, durable armor, and state-of-the-art defense technology. They rely on this, overwhelming strength, and firearms expertise to defeat their enemies.

Backpacks for this class resemble generators and ammo storage.

Characters in the game's story representative of the Tachyon powers tend to be plants whose innate abilities focus on defense.

Gameplay
The Tachyon Phase's abilities are split between four subclasses, which alter its ultimate ability, melee, throwable, and passives. For all subclasses, the following selectable abilities are universal to them:
 * Beam Shield: Detonates a small pod in front of you, releasing a thick curtain of particles that disrupt incoming fire. Can be walked through, but enemies who try to do so will be severely injured. Cooldown is affected by your Defense stat.
 * Keeper's Shield: Full-size shield. Has no special properties, but is great for halting advances on your positions.
 * Charger's Shield: Half-size shield. Standing behind the shield will slowly regenerate weapon magazines from reserves, even while firing.
 * Lift: A heavy blast of propellant from the IR Frame's jets provide a harsh vertical boost.
 * Strafe Lift: Emphasizes horizontal control over speed and height.
 * Burst Lift: Emphasizes speed.
 * Catapult: Emphasizes height.

Subclasses
For all three Phasers, each subclass element retains the same general theme, adjusted to the class's specialty.

A Phaser's second subclass unlocks at gear score 150. Its third subclass unlocks at gear score 250. Its fourth subclass, which is always representative of Shadow damage, must be unlocked by playing The Dark Mirror campaign.

Refer to the main articles for these subclasses for further perk information.
 * Fulminator: Electricity-based crowd control and durability subclass. Ultimate ability is the Electron Breaker, which overflows the user's fists with electricity, creating highly lethal and explosive discharges with every impact.
 * Starbreaker: Fire-based offensive and regeneration-oriented subclass. Ultimate ability is the Argide Buster, a dense beam of radiation and heat fired from a summoned cannon.
 * Betavoltaic: Acid/radiation-based defensive/debuff subclass. Ultimate ability is the Amphoteric Ward, an energized shield that can either be weaponized as a personal effect or dispersed into a strong, static barrier.
 * Nightsmith: Shadow-based DPS support/debuff subclass. Ultimate ability is the Twilight Sagaris, a large, heavyweight dark axe that can fell powerful foes in one swoop and sunder those that remain.
