Skulldash is a megawad and time-trial styled gameplay mod for GZDoom (3.2.0 and higher) created by Joshua O'Sullivan (Dragonfly). The original version, containing 32 levels, was released on 22 October, 2015, and ran on the Zandronum source port. This first release went on to win one of the 22nd Annual Cacowards.

In 2017, an expansion pack, entitled Skulldash: Expanded Edition was released, allowing the mod to be played in GZDoom, and featuring an additional eighteen levels created by O'Sullivan and various mappers from across the Doom community. The mod is intended to be played using the OpenGL renderer, with the effects of the software renderer ranging from sub-optimal visuals to major graphical glitches on some maps.

Gameplay[edit]

Skulltokens[edit]

In Skulldash, the player is tasked with reaching the exit of each level within a set time limit, collecting tokens (officially referred to as skulltokens) along the way in addition to fighting monsters to reach as high a score as possible. Each level requires the player to collect 75% of all skulltokens in the map. Most skulltokens are white in colour and add 100 points to the player's score, though some different-coloured variants are also included, each performing a different function when collected:

  • Green skulltokens provide the player with 25 armor points, and add 1,000 points to the player's score.
  • Red skulltokens provide the player with 25 health points, and add 1,000 points to the score.
  • Blue skulltokens add an extra five seconds to the remaining time, and add 500 points to the score.
  • Golden skulltokens are found rarely, but give the player 100 armor points, as well as adding 50,000 points to the score.

The exit area of the map will not open until the player has met the 75% collection requirement. If the player manages to collect every skulltoken, they will be rewarded with a high value health-item (usually a soulsphere or megasphere) at the exit, and their score for the level will be doubled. If the player fails to reach the exit in time, they will be automatically killed and have to restart the level.

Monsters[edit]

Skulldash features the original Doom II monster cast, unchanged from their original behaviour, as well as some new additions. Killing monsters will add to the player's score.

Score values of original monsters[edit]

Custom monsters[edit]

All custom monsters except the bosses, the shadow, grell, flesh spawn, blood skull, and gem turret are taken from Skulltag, modified only to implement the score mechanic.

Shadow
A dark, translucent imp-like monster with a fast movement speed. The shadow launches red projectiles with relatively low damage, and will not stop doing so until the player moves out of its line of sight. It has 80 health, and is worth 400 points.
Dark imp
A dark-skinned imp. It launches a fast-moving blue and purple projectile that deals similar to damage to the regular imp. It has 120 health and is worth 800 points.
Flesh spawn
Flesh spawns are small pink, spherical flying demons that could be described as the larval form of the cacodemon. Their only feature is the large mouth, which they use to attack. They can charge at the player similar to lost souls, or they can launch a miniature cacodemon projectile which deals 2-16 damage. They have 50 health and are worth 1000 points.
Blood skull
These flying skulls are covered in blood, which can be seen dripping to the floor beneath them. They attack frequently, launching a red projectile that deals 3-24 damage. They have 120 health.
Blood demon
Blood demons can be distinguished from regular demons by their darker colour. It has 300 health - twice that of the demon - but is functionally the same. Blood demons are worth 1200 points.
Grell
Grells are brown airborne demons similar in appearance to the cacodemons from Doom 3. They have 300 health and attack by launching a small green projectile that explodes on impact with the player, releasing a noxious green gas that deals damage over time. They are worth 2500 points.
Cacolantern
This cacodemon variant is marked by its orange skin. It fires a light blue projectile that deals the same damage as its original counterpart, but travels at twice the speed. The cacolantern has 800 health - twice that of the cacodemon - and is worth 3000 points.
Super shotgun guy
An addition to the zombie roster that is self-explanatory in function. Identifiable by their black and green armour, super shotgun guys are very dangerous at close range, dealing up to 75 damage before armour. They have 120 health and are worth 3500 points. Upon death, the super shotgun is dropped.
Hectebus
A dark grey mancubus. Like its original counterpart, it will attack three times in a single action, however it instead launches bright green fireballs that move 10% faster than those of the original, and deal 50% more damage. It also fires more fireballs at once, with a spread of four fireballs in each of the first two shots, and five in the third. The hectebus has 1200 health - twice that of the mancubus - and is worth 7500 points.
Belphegor
An upgraded baron of Hell that launches a volley of three projectiles, the same behaviour as a cyberdemon. The projectile differs only from the regular baron's in its speed, moving 33% faster. The belphegor has 1500 health, and is worth 10000 points.
Abaddon
This is a cacodemon variant with a black and dark grey appearance. It shoots two orange projectiles in succession, which have twice the speed and damage as the regular cacodemon projectile. Abaddons have 1200 health - three times that of the cacodemon - and are worth 12500 points.
Gem turret
Gem turrets appear as support for the seraphim. They are stationary, and attack by launching a single white projectile identical to that of the seraphim's, with a moderate firing rate. They have 50 health and are worth 500 points.

Bosses[edit]

Lava demon
This is the first boss monster, encountered at the end of tier two. It is a bright red-orange humanoid seemingly made entirely out of lava. It has 6000 health and is worth 100000 points.
Dark inquisitor
This is the second boss monster, encountered at the end of tier three. It is based on the inquisitor from Strife. It has 6000 health and is worth 5000 points.
Gate keeper
This is the third boss monster, encountered at the end of tier four. It takes on the appearance of the cycloid emperor from Duke Nukem 3D, with jet black skin. It has 6000 health and is worth 5000 points.
Overlord
Encountered in the final level of the main set, this airborne boss resembles a six-armed pain elemental, with black skin. It has 10000 health and is worth 10000 points. It has multiple attacks and its behaviour changes as it loses health.
Seraphim
Encountered in the community set, this boss is a winged knight in white armour. It has 27500 health and defeating it will reward the player with 2.5 million points. The seraphim has multiple attacks, and its behaviour changes over time.
Dark cardinal
Encountered in the community set, this is a flying top-half of a cyberdemon, with 20000 health. It has black skin and magical blue fire takes the place of the demon's lower half. Upon beating the cardinal, the player will receive one million points. The cardinal has multiple attacks and its behaviour changes over time.

Other custom things[edit]

In addition to the monsters, Skulldash contains the content definitions for other custom things from Skulltag, namely all weapons, spheres and runes, and also the red armor, which gives 200 armor upon pickup and absorbs 80% of damage.

Levels and music[edit]

Tier system[edit]

The levels of Skulldash are grouped into mini-episodes referred to in-game as tiers. There are five main tiers, plus an additional community tier that was added in the expanded edition. The tiers are scattered around different parts of the hub level, which the player is returned to after completing a level. Each tier is initially locked; the player must complete a tutorial level in order to unlock tier one. Every level in tier one must be completed in order to unlock tier two, and so on, however, the levels within a tier can be completed in any order, with the exception of boss maps, which themselves are locked until the completion of the tier's normal maps. Each tier also includes a bonus level, which is unlocked after the tier has been completed, but is not required to progress in the game.

The community tier is considered separate from the main game, and can be accessed as soon as the tutorial has been completed.
