Quake Champions: Doom Edition (also known as QC: Doom Edition or QCDE) is a gameplay mod based on Quake Champions featuring custom classes, weapons and monsters. It originally was designed for Zandronum 3.0, with compatibility for GZDoom from 1.8.6 to 4.3.3 and Delta Touch.

Current releases come with a fork of the Zandronum source port called Q-Zandronum providing improved netcode, Quake-style movement and Quality-of-Life improvements, whilst maintaining compatibility with Zandronum and GZDoom. QC:DE boasts balanced gameplay across the single player, numerous PvP and cooperative game modes.

It was granted the Multiplayer award at the 2018 Cacowards.

Main features[edit]

  • Can be played with its own fork, Q-Zandronum. A special patch is provided taking advantage of the new features of this engine.
  • Can be played as a standalone game. Resources from the Freedoom project are utilized to make this possible.
  • 31 unique champions, each with their own active and passive abilities.
  • 11 weapons from Quake Champions, plus one.
  • Monsters from Doom, Doom II, Doom (2016), Quake, Quake II and Quake 4.
  • Map completion bonuses (nicknamed "lootboxes").
  • Extremely flexible difficulty: apart from traditional skill levels, different classes can be harder or easier to play in single player.
  • Damage numbers show how much damage you deal to everything. They can be switched off, too.
  • Rocket jumping, crouch-sliding and nail climbing, it's almost like Defrag scene never died.
  • Zandronum 3.0 compatible. Use Doomseeker or any other server browser to find games in progress.
  • Delta Touch compatible.
  • GZDoom 1.8.6 to 4.3.3 compatible.
  • Player-versus-environment compatible -- and designed for that. This includes single player, multiplayer cooperative and survival.
  • Player-versus-player (PvP) compatible -- and rebalanced for that. Deathmatch, Team DM, Capture the Flag, Domination, Last Man Standing all supported.
  • Duel-oriented, with occasional tournaments commentated live by Quake Champions casters.
  • New PvP game modes: Freeze Tag, Elder's Soul (Terminator), InstaGib, Unholy Trinity, and more.

QCDE comes with two mapsets for Deathmatch and Last Man Standing modes: Aeon Deathmatch for QCDE (AeonQCDE.pk3) and QCDE maps (QCDEmaps2.7.pk3).

AeonQCDE is a version of AeonDM edited to contain QCDE weapons and specific map markers. QCDE mapset consists of 43 contributions created specifically for QCDE by DBThanatos, RoosTer, Mr.Enchanter, IvanDobrovski, Abysswalker, Mr.Rocket, Ivory Duke, and Killerkouhai.

Unofficial maps have also been made by mod's community, such as RoosTer's Invasion mapset.

Champions (Playable characters)[edit]

All champions have individual health/armor caps, referred to as stacks. Champions themselves are divided into three classes:

  • Light (A.K.A. squishies): Smaller than average hitbox, low stack, generally fast.
  • Medium: Standard doom hitbox, medium stack, medium speed.
  • Heavy (A.K.A. tanks): Big hitbox, large stack, slower movement.

The stacks are “lower” compared to Doom, and light champions seem rather fragile, since they have low caps for health and armor. However, this is countered by their abilities. Light champions have ways of healing or escaping dangerous situations — as opposed to tanks, whose abilities are more about dealing with danger face-to-face.

The fact that stacks are relatively low overall is compensated by healing items giving much more health than traditional Doom pickups, and armor being much more common. Therefore, it's possible to lose health quickly, but so long as an escape route is available, lost health can be gained back in a heartbeat.

Classes in single player[edit]

In GZDoom, player pawn size is always set to standard, so players don't have to worry about hitboxes.

For single player in older source ports, only “Medium” champions are recommended. Light Champion hitboxes are very slim, allowing them to fit through bars or other tight crevices where players aren’t supposed to fit. Conversely, Heavy Champion hitboxes are considerably bigger and won't fit in the tightest of places where the player might be expected to go. It's still possible to play any class, but if map progression is broken, the responsibility is on the player.

Regarding difficulty, playing single-player or cooperative with Medium champions is playing QCDE in “normal” mode. Playing with Light champions is more of a challenge, and playing with Heavy ones is a bit on the easier side because of their large stacks.

Active and passive abilities[edit]

Multiplayer-only class picker showing 31 classes available in QCDE.

Abilities define the play style of the characters. For example, Kane, being inherently fast, has even greater speed while crouch-sliding, which allows both to deliver firepower right into the enemy's lair and retreat, possibly using Stroyent Injection which instantly restores his health in case his plan goes awry. As the opposite example, Terminator hardly ever needs to retreat, as his ability to passively restore ammo alongside a freely triggered rocket barrage ensures that he can deal with any threat without slowing the pace.

Some ability effects differ slightly between PvE and PvP (Deathmatch, CTF and the likes). Usually, PvE abilities have a stronger, more pronounced effect, and a fittingly longer cooldown time between uses. This increases the value of "time shards"—the hourglass-shaped bonuses that reduce cooldown by 10%.

Monster replacement[edit]

Player faces an eclectic menagerie composed from custom monster themes made by community members.

The player can use monsters from Doom, Doom 4, Quake 1, Quake 2 and Quake 4. More than that, players can mix and match monster sets — for example, picking both Quake 2 and Quake 4 would be fighting against united Strogg forces.

All monsters emit damage numbers when hurt.

Monster randomization has two modes: classic, as known by the likes of Aeons of Death and other randomizer mods, and one theme per map, selecting only one of the enabled themes at random for each map.

Custom monster themes[edit]

QC:DE features an ACS-based API that allows third-party monster themes to be cleanly interfaced with the mod. As a result, over 40 monster sets have been developed by the community members, mainly porting monsters from other popular games into QCDE. Each monster set can be played exclusively, replacing all monsters, or in combination with other monster sets, built-in or third-party.

Several monster theme addons have been released officially by the mod's team, including Heretic, Marathon and Doom 3 monsters. A tutorial for making monsters compatible with QCDE is available on ModDB, as well as a template theme file to plug values into.


During single player or cooperative games, killing all monsters and finding all secrets on a map is rewarded with a random tiered bonus, represented by a lootbox. Like in Quake Champions, there are three reward tiers on this surprise mechanic: Backpack, Chest and Reliquary. Lootboxes reward player for map knowledge and perseverance during secret hunting.

Backpacks contain rewards that are immediately useful, such as a random weapon, an ammo refill, or a megahealth. Chests contain more significant rewards, such as a strong powerup to be given on the next map, or sometimes, even two. Reliquaries, the most prized lootboxes, contain permanent improvements such as max health or max ammo increase.

In multiplayer games, every player gets their own lootbox once all monsters have been killed and all secrets found. It is therefore especially beneficial to party as a whole to complete the map perfectly.

It's worth noting that at no point do surprise mechanics of this mod ever cross ways with real world money. The lootboxes of QC:DE are completely free.

Original soundtrack[edit]

Official soundtrack album cover

Soundtrack consists of the album Augmented of original metal music by Michael Markie and covers of songs from Doom, Quake 1 and 2 and Blood.

Excerpts have been featured as outro music for released videos, and as background music for Kane deathmatch video.

Competitive scene[edit]

Owing to its Quake roots, Quake Champions: Doom Edition has developed a competitive scene. Several duel tournaments with monetary prizes have been held. The most successful series, TastyCups, has seen 7 tournaments to date, the latest one in May 2020. TastyCups are organized and casted by Alex "Jehar" Popa, known for also casting Quake Champions tournaments.
