THE GAME
I made MORSO for 1v1 games with friends at LAN parties. It is my first Dota custom game, inspired by Custom Hero OMG. Since v0.9 it also has 2v2 team games and tournaments.
Subscribe on the Workshop, launch MORSO in the Dota 2 Arcade and choose the 1v1 or 2v2 map. In 2v2 everyone picks a team on the first screen. The host chooses Ladder, Tournament or Unranked (what the modes mean) and the draft, then everyone readies up. You can chat in the lobby, and teams have their own chat from the bans through the draft.
Classic: ban a hero and an ability, pick a hero, then choose four of 15 offered abilities, ultimates included. Shared (new in v0.9.7, Unranked): both sides draft from one public pool in turns (how it works).
Buy items, control the river and adapt your abilities during the match. The first tower, or 2 kills (4 team kills in 2v2), decides it.
THE MAP
Neutral camps sit on both sides of the river. The upper area has two Ancient camps, a Lotus Pool and the Secret Shop.
Aegis and Aghanim’s Blessing. One chance: he does not respawn.
Found in the mist at the bottom right of the map. Drops Aghanim’s Shard.
River runes grant free ability changes, and so does every death of your hero. You can also buy a new ability during the match.
SEASON 0 · OPEN BETA · ENDS 31 DECEMBER 2026
Everyone starts at 1000 MMR, shared by 1v1 and 2v2, and every player's game confirms the result (how). Seasons last a year (seasons). Sign in for your match history.
Checking ladder status…| Rank | Player | MMR | Wins | Losses | Win rate |
|---|
Rated ladder matches update this table and the in-game statistics. Solo practice does not count.
Steam-linked players appear after 3 rated matches. Some games are recorded without changing MMR, repeated games against the same opponent count half, and leaving a started match costs extra MMR. The full rules: how results are checked, how MMR changes, leaving a match and seasons. Report suspicious records by email. Link your Steam account to play for MMR, appear on the leaderboard and protect your ladder record.
SEASON 0 · OPEN BETA · ENDS 31 DECEMBER 2026
Season 1 and MORSO 1.0 start on 1 January 2027, and every season after that lasts one calendar year. When a season ends, MMR returns to 1000 and the season's ladder record starts again; lifetime game statistics stay.
The global top 3 receive a season award, a desk medal in gold, silver or bronze, on their profile. Every other player with at least 3 rated matches in the season keeps the rank medal they finished with.
DEVELOPMENT LOG
Changes to the map, abilities and interface. If something breaks, please tell me on the Workshop page or by email.
Built for Dota 7.41f. Small Shared Draft tweaks: the announcer calls your turn, a bigger hero pool and more time to look at the abilities.
Built for Dota 7.41f. Shared Draft is easier to follow: a big turn banner with a timer, hero innates on the cards and a new look. New music, and hero stats on morsomid.com.
Built for Dota 7.41f. A new draft mode for Unranked: both sides pick from one shared pool, in turns, and every pick is public. Smaller download, and fewer false alarms in the fair-play check.
BEFORE YOU READY UP
Yes. You need Dota 2 and the free MORSO Workshop subscription. No paid gameplay advantages.
Choose the 2v2 map in the Arcade. On the first screen everyone clicks TEAM A or TEAM B, and a coin toss decides which team plays Radiant. The tower has 1.5 times the 1v1 health and the first team to four kills wins. The lobby chat has ALL and TEAM channels, teammates have their own chat from the bans through the draft, see each other's bans and abilities live and both heroes in strategy. 2v2 Ladder needs two Steam-linked players on each team and uses the same MMR as 1v1.
Season 0, the open beta season, runs until 31 December 2026. MORSO 1.0 and Season 1 start on 1 January 2027, and from then on every season lasts one calendar year. When a season ends, everyone's MMR returns to 1000 and the season's ladder record (rated matches, wins and losses) starts again from zero; lifetime game statistics stay. The global top 3 receive a season award on their profile, and every other player with at least 3 rated matches in the season keeps the rank medal they finished with as a memento of that season.
Yes, solo practice is useful for learning the draft and testing builds. It does not count towards ranked MMR.
In Ladder and Tournament games you have two minutes to reconnect. After that, in 1v1 the other player wins; in 2v2 the match continues two against one. Whoever leaves pays 25 extra MMR on top of the team's result, and leaving repeatedly within 7 days adds a ladder cooldown: first a warning, then 15 minutes, 1 hour, 6 hours and 24 hours. If your game stops reporting to the site in the middle of a Ladder or Tournament game, the match ends without a result; the first time in 7 days is free, after that it counts like leaving. Cooldowns only block Ladder; Unranked stays open. A moderation ban blocks every mode.
If every game stops responding without a result, the lobby host's departure is recorded without an MMR change, because the host's computer runs the match. In 1v1, a host who leaves a started match after at least 5 minutes twice within 7 days loses the second one.
The host registers the match, but each player's own game joins it and confirms the winner directly with morsomid.com. The host never receives another player's confirmation key. A result changes MMR only when the games agree, or when a game confirms after another stopped responding. Every player must be Steam-linked; linking once per computer (renewed automatically while you play) also protects your account, so only your linked game can play ladder matches as you.
The leaderboard lists Steam-linked players with at least 3 rated matches. Player-hosted games cannot be fully verified; report suspicious records by email. Earlier open-beta results (v0.8.1–0.8.2) are not shown.
Everyone starts at 1000 MMR. Beating a stronger player is worth more; 1v1 and 2v2 share one MMR. In 2v2 each player's change is calculated from their own rating against the other team's average, so carrying a lower-rated teammate earns you less and them more. Tournament games change MMR only in ranked tournaments.
Games under 2 minutes are recorded without changing MMR; a short tournament game still counts for its series. After 3 rated games against the same opponent in a week, each further result counts half. Leaving a started match costs extra MMR (leaving a match), and MMR resets when a season ends (seasons).
Hacking, cheating, exploiting bugs or arranging results with another player can lead to a ban from MORSO, removal from the leaderboard or other measures. Suspicious results are reviewed; report them by email.
Email me or leave a comment on the Workshop page. Feedback and ideas are welcome too. For a bug, say what happened and roughly when, and include the match ID from the top-left corner of the screen and your hero and abilities. Please remove private information from any console logs. The in-game lobby has the same details under CONTACT.
MADE BY ONE DEVELOPER
MORSO is designed, built and tested by a single developer in spare time. I try to release patches every week, so every comment, bug report and match helps.
Humble thanks to the active beta testers so far:
If you enjoy my work and want to see more of it, you can support development with a coffee. Support is completely voluntary and gives no gameplay advantage: MORSO stays free for everyone. As a thank-you, supporters get a blue glowing player card and name in game and on this site, the MORSO Supporter award and the Supporter role in the MORSO Discord. Write your MORSO ID from My stats in the coffee message. You can make the message private; I still see it.
