Generate a finished BAR map in a few seconds
Choose a format, a size and a style. Eclipse builds the whole map — heightmap, textures, metal spots, geo vents, reclaim and trees — writes it into your BAR maps folder and starts a game on it. 20 styles, 13 biomes, 8×8 to 32×32, 1v1 up to 8v8 and FFA.
Beyond All Reason has to be installed first — Eclipse does not include the game. BAR is free at beyondallreason.info. Eclipse is an unofficial project, not affiliated with the BAR team.
What you set, and what it builds
The terrain, symmetry, spawns and resources come from the Neroxis map generator that Forged Alliance Forever has used for years. Eclipse converts its output into a real Beyond All Reason map.
The settings
Format — 1v1, 2v2, 3v3, 4v4, 5v5, 8v8, FFA 4 or FFA 8, or set players per team and the number of teams directly. Up to 16 start positions.
Map — size from 8×8 to 32×32 with a recommendation per format, one of 20 styles (valleys, plateaus, rivers, islands, Setons-like and others) or a custom mix of terrain, biome and reclaim style, and the symmetry: mirrored, point, quad or diagonal.
Economy — how much metal the spots next to your start are worth, how rich the richest contested spot gets, whether all spots are equal, and how much reclaim is lying around.
Both sides get the same terrain
Maps are built from a symmetry rule, not from scattered noise. The conversion to BAR keeps it: the heightmap filters, the cliff sharpening and the metal-spot merging are all symmetric.
Mirrored metal spots are worth the same
BAR metal spots differ in value, and Eclipse varies them — but only from numbers that are identical for mirrored spots. Spots that match are grouped and given the group average, so rounding cannot hand one side a richer start.
Metal is placed like a BAR map
The spots next to your start keep the standard income, so your opening is the normal one. Spots get richer with distance from every start, poorer in a crowd, and richest when lone and contested. The default range is 2.0–3.5.
Vehicles are checked
BAR vehicles climb far less than bots. The map is scaled vertically so generated ramps stay drivable while cliffs stay cliffs, and if a map is passable for bots but not for tanks the terrain is flattened in steps until they get through.
Reclaim is budgeted
Supreme Commander maps are full of reclaim and BAR maps are not, so nothing is copied over blindly: rocks and wrecks are kept up to a budget of about 600 metal per start position. Mirrored rocks are kept or dropped together, and experimental wrecks are never placed.
Trees that fit the biome
Snow pines on frozen maps, birches and green pines on river maps, palms and kapok in the tropics, cacti in the desert, dead trees on the burnt red worlds, crystals on the crystalline ones. They come from the shared feature sets BAR mappers use, downloaded once.
Every texture is procedural — noise and shading maths, no painted art and no generated images. It will not match a map somebody spent a month on: the cliffs are softer, because the heightmap is upscaled from a Supreme Commander one, and the ground has no hand-painted detail. Generation takes about 4.6 seconds for an 8×8, 7 for a 16×16 and around 20 for a 32×32.
Where the maps are made and played
Eclipse is a Windows launcher that sits beside your Beyond All Reason install. It generates maps, keeps them in a library, and starts a game on one — offline against the AI, or online in a room with other people.
Your map library
Generated maps stay. The preview draws the real metal spots, geo vents and start positions with the game's own icons, and lists the map's size, player count and where each team starts. From the library you can start a game on a map, or delete it.
Every map keeps the code it was built from, so any map can be rebuilt exactly — by you, or by somebody else on another computer.
Offline or online
Offline skirmish vs AI generates the map and starts BAR on this computer right away. No account, no sign-in.
Online game opens a room on the Eclipse server that other people can join. The map, the game version and the engine version download by themselves while you sit in the room; you press Ready, and Eclipse starts BAR when the host starts the game.
Rooms, chat and parties
Teams with faction icons, flags and ratings, eight start-box presets or your own drawn on the minimap, votes, a public chat channel, whispers, a friends list and parties.
Replays and keybinds
Your local replays with map, date and engine version, playable in a click — and a full editor for BAR's shortcut keys with a searchable list of actions.
The official servers too
A read-only view of what is running on the official BAR servers, with one button to open BAR and join. Eclipse never asks for your BAR account.
How to install
Windows 64-bit, about 60 MB, Java included. No administrator rights needed.
Install Beyond All Reason and start it once
Skip this if you already play. Eclipse does not contain the game — it uses the copy on your computer. BAR is free at beyondallreason.info.
Download and run EclipseSetup.exe
Windows will warn about an unknown publisher, because the file is not code-signed. Choose More info → Run anyway. The installer downloads the package, checks its signature and starts the launcher.
