Thank you again for your patience and continued support of DOOM Eternal --- ##### Horde Mode Compete for the highest score by battling wave after wave of demons across three Missions from DOOM Eternal and The Ancient Gods – Parts One and Two* in this challenging new single player game mode. You’ll need to keep your wits about you and your skill sharp. Like a classic arcade game, there aren’t any checkpoints, you start with just 3 extra lives - but there are more to earn as you progress. You begin with only a fully mastered Combat Shotgun, unlocking a new weapon at random as you complete each Arena Round. Earn new Milestones and unlock loads of cool new customization items as you progress! _*All Horde Mode content is available to players who own any DOOM Eternal product configuration, including standalone versions of The Ancient Gods - Parts One, Part Two, and or the Year One Pass_ ##### Structure Each Horde Mode Mission consists of the following Rounds (pictured above): - **Arena Round **- Arena combat encounter with waves and waves of demons - **Blitz Round** - Kill as many demons as you can before time runs out - **Bonus Coin Round (optional) **- Collect as many coins as you can before time runs out - **Traversal Round** - Navigate a traversal puzzle and collect as many coins as you can before time runs out - **Bonus Blitz Round (optional)** - A Blitz round but with Super Heavy demons and Onslaught (damage multiplier) power-ups! ##### Scoring Your score is tallied at the end of each Round. You are awarded additional points for any remaining Extra Lives and BFG Ammo - Every demon you kill that isn’t a Zombie, a Spirit or summoned by an Archvile gives you points - Bigger demons are worth points more than smaller ones - Bounty demons are worth more than standard ones but decrease in value over time - Earn more points by completing Mission Challenges (completing all of them rewards bonus points) - Picking up coins in Traversal and Bonus Coin Rounds reward points (Gold > Silver > Bronze) ##### Progression You begin Horde Mode with: - 3 Extra Lives - A fully mastered Combat Shotgun - The Chainsaw, all Equipment and Dash - All Perks, Runes and Sentinel Crystal Upgrades - Another fully mastered gun is awarded at random on completion of each Arena Round - Special weapons are given at the start of certain Arena Rounds* - Completing Milestones unlocks new customization items - Additional Extra Lives are awarded by completing Blitz Rounds, Bonus Coin Rounds, Bonus Blitz Rounds, Combat Arena Rounds 1 and 2 in The Holt and by killing the required number of demons in Blitz and Bonus Blitz Rounds. They can also be acquired in level during any Traversal Round _*The Sentinel Hammer in The Holt Horde Mode Level requires 4 charges (2 more than in The Ancient Gods – Part Two)_ ##### Leaderboards - There is a different Leaderboard for each Difficulty - Your score gets uploaded to the Leaderboard at the end of each run - Your rating is based on your score - The top 10 players on the Leaderboard get Slayer Medals ##### Rewards Galore There are so many amazing earnable rewards in Horde Mode, that instead of listing them all via text, we thought it would be better to show you: _So..._ _...many..._ _...rewards._ --- ##### New Master Levels Update 6.66 includes two new Master Levels, Mars Core and The World Spear*.
