The Battle of Polytopia: Moonrise is the current version of The Battle of Polytopia. Moonrise was initially released on Steam with the release of the Steam port on August 4, 2020. Moonrise was later released to mobile as an update on November 23, 2020. Moonrise uses the Unity game engine, while previous mobile versions of Polytopia used the Adobe AIR system. The developers chose to port the game to Unity in order to ease future development. Because Unity is a very common game engine, using Unity allowed the development team to more easily hire programmers. However, the port from Adobe AIR to Unity caused a lengthy delay in the release of the Steam port and an unprecedented hiatus in gameplay and content updates.
Notable new features of Moonrise include:
- A new multiplayer server for online multiplayer games:
- Lobby for random matchmaking.
- Player avatars (players choose from randomly generated options).
- Turn time limit options ranging from 5 minutes to 7 days.
- Every move is uploaded to the server in real time, preventing players from "turn resetting" (where in online multiplayer games, players could undo the actions they had taken that turn or reset the game's spawn if hosting the game, given that the player had not saved the game by returning to the main menu).
- Players can see opponents' moves in real time instead of having to wait for their turn.
- Players can add opponents by their Steam username (friend codes are not used in the Steam port).
- Larger maps with up to 900 tiles. (Larger maps were known to cause performance issues in the Adobe AIR version.)
- Map customization options (“Dryland,” “Lakes,” “Continents,” “Archipelago,” and “Water World”).
- Mirror matches where multiple players (or bots) can pick the same tribe.
- A new world generation system that eliminates island spawns, among other changes.
- General bug fixes.
Some of the gameplay changes (excluding those considered "new features") introduced in Moonrise are listed below. (This list is incomplete.)
- Before Moonrise, the push order for forced spawns was consistent for every incident. In Moonrise, the push order varies depending on the direction the unit was previously moving in.
- Before Moonrise, units with 0 attack, namely the Mind Bender and the Mooni, could not capture enemy cities. In Moonrise, those units can do so, which makes the 0.1 attack of the Ice Archer redundant.
- Before Moonrise, disabling tribes was purely local and did not affect other players in online multiplayer.
- Before Moonrise, the resources bonus for meeting a tribe after turn 10 was 10 stars.
- The Perfection difficulty bonus was changed in Moonrise. The difficulty bonus before Moonrise increased linearly per additional opponent. The base difficulty bonus was 100% for Easy opponents, 120% for Normal opponents, 140% for Hard opponents, and 180% for Crazy opponents. An additional 10% bonus was added per opponent (including the first opponent). In Moonrise, the difficulty bonus increases logarithmically per additional opponent.
- Before Moonrise, as player IDs were used to add friends in multiplayer, attempting to add yourself as a friend would produce the following message:
Submitting an empty player ID would produce the following message:
Me, myself & I
Seems like you tried to add yourself as a friend. That might sound like a nice thing to do but it would add an existential layer to the game that we cannot handle at the moment. Please submit a player ID of someone else.
The player ID you entered was complete empty! You should not try to make friends with the void, it is a very lonely path.
