Jamestown/Ships

Classic ships

Beam

Beam
	Description: "Forward beam and spread shot. Sir Walter's conveyance."
	Vulcan Shot: A forward spread shot in 5 directions. While the straight forward missile's sprite looks different than the others' and may have been intended to deal more damage, their damage is all the same.
	Special Shot: A straight laser that functions much like the laser from the DoDonPachi series. Shot and Special can not be used simultaneously.
	Stats: movement speed: 6 (unfocused), 3 (focused) vulcan shots: 60dps; damage=1, frequency: 5 shots every 5 frames special laser: 87dps; damage=1.45, frequency: damage every frame

Gunner

Gunner
	Description: "Directional vulcan shot. John Smith's conveyance."
	Vulcan Shot: Forward shot and directional shot. The bullets shot forward can have three different speeds which are determined randomly. The directional shot angle will not be changed while only holding the shot button.
	Special Shot: Forward shot and directional shot. However, while special is held, the directional shot angle will be changed to the direction the ship is moving in. The change is not immediate. Special shot is prioritized over vulcan shot.
	Stats: movement speed: 6 forward shots: 27.84dps; damage=0.928, frequency: 1 shot every 2 frames directional shots: 50.75dps; damage=1.0875, frequency: shot alternates between firing for 8 to 20 frames and not shooting for 2 to 6 frames

Charge

Charge
	Description: "Piercing orb of charged energy. Virginia Dare's conveyance."
	Vulcan Shot: Straight shot.
	Special Shot: Releases a slowly moving piercing orb. Its size and damage depends on how long it was charged. It takes 2.5 seconds to charge fully. The charging occurs automatically regardless of whether the vulcan shot is used or not. If the orb continuously collides with a target between dealing damage, any hit after the first hit will deal double the damage of the first hit. Once it stops colliding with a target, this process resets. It's possible to continuously release small orbs once charged by holding the Special button.
	Stats: movement speed: 6 vulcan shots: 30dps (intended: 40dps); damage=2, frequency: 1 shot every 4 frames (intended: every 3 frames) special shot (small orb): ~2.727*n dps; damage=2.5, recharge: 55 frames, damage frequency: damage every 9 frames (intended: every 8 frames) special shot (medium orb): ~5.097*n dps; damage=8.75, recharge: 103 frames, damage frequency: damage every 9 frames (intended: every 8 frames) special shot (full orb): ~5.960*n dps; damage=15, recharge: 151 frames, damage frequency: damage every 9 frames (intended: every 8 frames) n: the amount of times the base damage gets dealt. Note that if an orb hits enemies in quick succession, any hit after the first deals double the amount of damage as the first hit. This means that for 2 successive hits: n=3 and for 3 successive hits: n=5, etc...

Bomber

Bomber
	Description: "Detonate shots mid-air. Joachin Gaunz's conveyance."
	Vulcan Shot: Straight shot of vulcan bullets with below average speed.
	Special: Causes an explosion at the position of all of the ship's vulcan bullets and the ship itself. The vulcan bullets get destroyed by this but are not necessary for the special. Holding special will make the ship continue to fire bullets which immediately explode in front of the player ship.
	Stats: movement speed: 6 vulcan shots: ~51.43dps; damage=6, frequency: 1 shot every 7 frames (intended: every 6 frames) special explosion: ~126.43dps (intended: 147.5dps); damage=14.75, frequency: 1 shot every 7 frames (intended: every 6 frames) Each explosion only deals damage once.

Treason ships

Gunpowder

Gunpowder
	Description: "Three barrels can be thrown as bombs or fire bullets. Percy's Conveyance"
	Vulcan Shot: Straight shot fired from the ship and every barrel orbiting around it.
	Special Shot: Launches one of the barrels forward. Releasing the special button makes that barrel explode. Every 100 frames, a barrel will be added to the ship. If the ship already has the maximum amount of 3 barrels, no new barrel will be added. However, this also means it's possible to obtain a new barrel right after firing one away.
	Stats: movement speed: 6 ship shots: 21.6dps (intended: 25.2dps); damage=2.52, frequency: 1 shot every 7 frames (intended: every 6 frames) barrel shots: 10.8dps*n (intended: 12.6dps*n); damage=1.26, frequency: n shots every 7 frames (intended: every 6 frames) barrel explosion: 3.78dps*m (37.8dps potential for single target); damage=6.3, max AOE hits: 10, recharge: 1 barrel every 100 frames, collision frequency: 1 collision every 4 frames n: number of current barrels m: number of collisions with each target Damage dealt by barrel explosions scales differently with more players. It's divided by 1+(players-1)*0.28333 instead of 1+(players-1)*0.5666.

Treason

Treason
	Description: "Speed around the battlefield and launch seeker missiles. Fawkes' Conveyance."
	Vulcan Shot: Straight shot.
	Special Shot: While the special button is held, the two pods next to the ship charge up to 4 missiles and the ship speed is reduced significantly. Releasing the special button launches all charged missiles. At full charge, the damage dealt by each missiles is multiplied by 1.5. At launch all missiles target enemies that they will home in on and can only collide with those. The first selected targets are enemies or obstacles in front of the ship. However, the ship will not release an excess amount of missiles on a target. If two missiles are enough to destroy the first target, the following missiles will have different targets. Walls in Croatoa that aren't targetted obstacles are ignored by the missiles. The precise targetting logic has yet to be fully understood.
	Stats: movement speed: 9 (unfocused), 4 (focused) vulcan shots: ~51.43dps (intended: 60dps); damage=6, frequency: 1 shot every 7 frames (intended: every 6 frames) missiles (1 charged): 20dps; damage=10, recharge: 30 frames missiles (2 charged): 24dps; damage=10, recharge: 50 frames missiles (3 charged): ~25.71dps; damage=10, recharge: 70 frames missiles (4 charged): 40dps; damage: 15, recharge: 90 frames

Ghost

Ghost
	Description: "Create a ghost to fight for you & wield a long blade. Catesby's Conveyance."
	Vulcan Shot: Straight and sideways shot if the ghost is not active. Sideways shot is much stronger. If the ship's ghost is currently summoned, the shot is replaced with a long blade aimed forward. The ghost shoots its bullets regardless of whether the shot button is held.
	Special: The special input is used to summon, reposition and dismiss the ghost. While the ghost is not active, pressing special will summon the ghost at the ship's location. Pressing special while the ghost is active will call the ghost to move to the ship's location at that moment. Pressing special while the ghost is still repositioning (essentially double tapping) will dismiss the ghost.
	Stats: movement speed: 6 vulcan shots forward: ~17.14dps (intended: 20dps); damage=1, frequency: 2 shots every 7 frames (intended: every 6 frames) vulcan shots sideways: ~42.86dps (intended: 50dps) on each side; damage=5, frequency: 1 shot every 7 frames (intended: every 6 frames) on each side ghost shots forward: ~17.23dps (intended: 20.1dps); damage=0.67, frequency: 3 shots every 7 frames (intended: every 6 frames) ghost shots backward: ~51.43dps (intended: 60dps); damage=[3 (big shot), 1.5 (small shot)], frequency=1 big and 2 small shots every 7 frames (intended: every 6 frames) sword: 54dps (intended: 72dps); damage=3.6, collision frequency: collision every 4 frames (intended: every 3 frames) The decompilation reveals that the blade's dps was explicitly intended to be 72. However, just like many other shot cooldowns in Jamestown+, the cooldown lasts 1 frame longer than it should.

Fortune
	Description: "A randomly-chosen ship from Classic & Treason ships. Fortune's Conveyance"
	At the start of each stage and every time the player dies, this ship will be switched to a random ship from the Classic and Treason ship collection.

Armada ships

Lazar A (Drop Beam)

Lazar A (Drop Beam)
	Description: "Customizable conveyance with stolen Spanish beam technology. Deploy a stationary beam cannon. The Castaway's [A] conveyance."
	Special: [...]
	Stats: movement speed: 6 [...]

Deltatime and cooldown oversight in Jamestown+

Many ships in Jamestown+ suffer from a bug that causes them to have less dps potential than intended. In Jamestown+, the delta time value for gameplay logic was changed from slightly above 1/60 to slightly below 1/60. Because of this, many shot and collision frequencies take one frame longer than intended. This page will list the intended cooldowns and the resulting intended dps values in brackets in those cases. The original Jamestown does not suffer from this, so the intended frequency and dps values hold true for that version.
