Classic quirks¶

The original game's bugs, as a player meets them. The rewrite fixes most of them by default; run it with --preserve-bugs to bring every fixed one back. A few stay in both modes. The # column links each one's full write-up in Original bugs; the last column links the page that covers it.

Gameplay¶

#	Quirk	In the original	Rewrite	Page
1	Gun-number drop bans	Some bonuses never drop while player 1 holds a matching gun: Nuke with the Pistol, Freeze with the Submachine Gun and more.	Fixed	Bonuses
2	Dud Greater Regeneration	Taking it does nothing.	Fixed: heals twice as fast as Regeneration	Perks
3	Bandage multiplies	Health is multiplied by 1–50, so it nearly always fills up.	Fixed: heals 1–50 HP	Perks
5	Empty reloads	A reload sped up by Stationary Reloader can finish with an empty clip: one shot per reload.	Fixed	Perks
17	Clumped swarmers	At some clip sizes, 6 with Ammo Maniac, every Mini-Rocket Swarmer flies on one heading.	Fixed: an even fan	Weapons
18	Quiet Highlander deaths	A Highlander death skips Final Revenge and the death sound.	Fixed	Perks
20	Homing at nothing	With nothing to chase, Shock Chain and Seeker Rockets steer at a leftover creature, dead or alive.	Fixed: they stop retargeting	—
24	The G key	Holding G while firing grants 10 s of Fire Bullets.	Ignored	Bonuses, Secrets
27	Leaky Death Clock	Enemy shots still hit for 10 during Death Clock.	Fixed	Perks
32	Ghost enemy shot	Until the session's first Shock Chain ends, an occasional enemy shot passes straight through you.	Fixed	—
33	Double carrier drop	A bonus carrier killed twice over, as by a rocket and its blast, drops its bonus twice.	Fixed	—
38	Quest difficulty leaks into Survival	A Hardcore box left ticked on the quest list toughens Survival's milestone waves and the Tutorial's creatures; quitting a retried quest from the pause menu eases them instead. Either way the run lands in the normal Survival table.	Fixed: both apply only to quests	High scores

Co-op¶

Most co-op quirks come from the original reading player 1's state where it meant the player in question.

#	Quirk	In the original	Rewrite	Page
6	Points conversion	Only player 1 standing near a Weapon drop turns it into Points.	Fixed	Bonuses
7	Regeneration	Heals only player 1, twice as fast with two players.	Fixed	Perks
8	Racing heart	Player 2's heart icon races whenever player 1 is low.	Fixed	—
9	Silent hits	With player 1 dead, player 2's pain and death sounds can go missing.	Fixed	—
11	Crosshair perks	Doctor, Pyrokinetic and Evil Eyes follow player 1's crosshair only.	Fixed	Pyrokinetic, Evil Eyes, Doctor
12	Jinxed accidents	The 5 HP accident always hits player 1.	Fixed: a random living player	Perks
13	Shared Fire Bullets	Either player's Fire Bullets converts both players' shots.	Fixed	Bonuses
14	Pyromaniac offer	Pyromaniac is offered only while player 1 holds the Flamethrower.	Fixed	Perks
15	Joystick hat	Player 2's hat aim reads player 1's hat.	Fixed	—
16	Pistol drop bonus	The extra 1-in-5 drop roll for Pistol holders checks only player 1's gun.	Fixed	—
19	Computer targets	Computer-controlled players can stick to a worse target.	Fixed	—
23	Plaguebearer	Only player 1 infects creatures by touch.	Fixed	Perks
40	Reload key	The reload key does nothing with two players: guns reload only when the clip runs dry.	Fixed	Co-op

Sights, sounds and menus¶

#	Quirk	In the original	Rewrite	Page
21	Death grunt	1 trooper death in 4 plays a pain grunt instead of a death cry.	Fixed	—
25	Hidden bonus timer	Re-picking a bonus can leave its timer panel off-screen for seconds while it runs.	Fixed	—
28	Invisible bullets	Bullets show only their trails, plasma shots only their glow.	Fixed: bullets and pellets show heads	—
29	Stray list clicks	With a list open, a click anywhere picks its last hovered row; on High scores that can switch the mode or filter.	Fixed	—
30	Typ-o hit %	Typed words carry over between Typ-o runs in one session.	Fixed: each run counts its own	Typ-o-Shooter
31	Resting aim stick	Letting go of the Dual Action Pad aim stick swings your gun to face left, and a drifting stick twitches it.	Fixed: a 0.2 dead zone	—
34	Fire Bullets glow	Fire Bullets shots usually lack their glow; with the screen full of shots, every shot can glow.	Fixed	—
35	Rocket flash	Rocket blasts flash the whole effects sheet: a ring down-right, specks up-left.	Fixed: a soft glow	—
36	Ion arcs	Ion chain arcs end in a straight cut across the creature.	Fixed: round ends	—
39	Missing pickup rings and bursts	Heavy blood from Bloody Mess or a large Freeze corpse shatter fills the effect pool, so pickup rings, hit cores and bursts vanish.	Fixed	—

Kept in both modes¶

#	Quirk	In the original	Rewrite	Page
4	Original text	Typos such as Fire Caugh and Persistence will be rewared.	Kept	—
22	The Killing's order	Quest 3.3 runs a fixed cycle: the same edges in turn, nests on waves 5 and 10.	Kept	Quests
37	Survival after 15:00	Spawning grows without limit until the arena holds 384 creatures.	Kept	Survival
—	Swapped quest score files	Normal quest scores save to `questhcM_N.hi`, hardcore ones to `questM_N.hi`.	Kept	High scores
—	Typ-o score file	Typ-o has no file name of its own, so its scores save to `scores5\unknown.hi`.	Kept	Local high scores

Not on the bug list yet¶

Quirk	In the original	Rewrite	Page
Every run makes the table	Every run is saved. Past 99 runs, each new one replaces the weakest listed score, even when it scores lower.	A true top 100	High scores
Formation tails	The last member of most rings, chains and grids is a 20 HP alien, and only it gets hardcore and retry scaling.	Kept	Quests

Two entries in the bug list, 10 and 26, are left out because no player can see them.
