The downloads and Nova are behind the subscription

The client pack, the league network ID and every version of Nova come with a paid subscription at five dollars a month. A free account can watch every replay, keep a profile and back other players. It cannot download anything or reach the network.

Read this first

There are two different game clients here and they cannot see each other. The modern client Blizzard gives away plays humans. The older 1.16.1 client is the only one that can play our bots. Pick your track below.

Step 01

Pick your track

The two clients are not network compatible, so this is the one choice that decides everything below. Most people start with the human brackets, because the client is a free download straight from Blizzard and there is nothing to hunt for.

Why the bots need a sixteen-year-old client

Nova runs on BWAPI, the community framework every StarCraft AI is built on. It hooks into the 2009 build. Blizzard added anti-cheat protection in the 2017 patch that shuts BWAPI out, so Nova cannot run on the current client and never will. That is why the bot track is separate, and why nothing on this page can make a modern install play Nova.

Good news

Both tracks, one network, one approval

You do not join anything twice. The league network carries both clients, so once we approve your PC you are set for human brackets and bot nights alike. Install both games side by side if you want, run whichever one that evening calls for, and nothing on your end changes when you switch.

Step 02

Get the client for your track

Install whichever one matches the track you picked. You can have both on the same PC if you want to do both, and they will not interfere with each other.

Human track · from Blizzard StarCraft: Brood War, current version Blizzard gives the game away. One installer, no key, and it is the same client the rest of the league uses for weekly brackets.

Bot track · version 1.16.1 StarCraft 1.16.1, the 2009 build The only version our bots can run on. Blizzard stopped distributing it years ago and does not offer it anywhere today, so there is no official download button we can point you at. required for Nova in every race How to get it

Where people get it, and what we will not do

We do not host the game ourselves. It is Blizzard’s to give away, not ours, and a league that hands out someone else’s game does not last long. If you still have an old disc or an old install, that is the cleanest route. Otherwise the StarCraft AI community keeps archived copies of 1.16.1 for exactly this purpose, and the setup guide walks you through pointing one at our bot pack. Ask in Discord and someone will talk you through it.

Step 03

Install ZeroTier

The classic game only finds opponents on a local network. ZeroTier builds a private one across the internet, so your PC and the league host behave as though they are on the same router. It is free, and only devices we approve can see anything.

Step 04

Join the league network

Open ZeroTier, choose Join Network, and paste the league ID. Your device shows up in our list as pending. We approve it, usually within the hour, and you are permanently on the network from then on.

League network ID

Subscribers get the network ID in their welcome email. It is not published here, because a private LAN that anyone can look up is not private.

Subscribe to get it

After you join, register for a bracket or email us your ten-character device ID so we know which pending device is you. Nothing else on your PC is visible to the league, and the network carries game traffic only.

Step 05

Add the league pack

The maps we play on and the shared display and speed settings. The map pack works on both clients. The Nova pack is bot track only, and it is the piece that actually brings Nova to your machine.

From us · both tracks Opleague Map & Settings Pack The full league map pool, plus a config that locks the game to windowed mode at a sane size and a fixed speed so nobody has an advantage. opleague-pack-s1.zip · 18 MB · 9 league maps + tournament pool Subscribers only
From us · Nova track only Nova Pack Nova in all three races, plus three sparring partners, BWAPI and the launcher that runs them. Needs the 1.16.1 client from step two. Will not do anything on the current Blizzard client. opleague-bots.zip · 62 MB · 6 bots, all three races Bots are open-source community projects, bundled with their licenses. Subscribers only

Check it all works

Run these four before your first bracket, not five minutes before it starts.

  1. The game opens and shows the version you expect
    The version sits in the bottom corner of the main menu. Human track, anything current is fine. Bot track, it must read 1.16.1 exactly.
  2. ZeroTier shows the league network as OK
    Hover the tray icon. Pending means we have not approved you yet, so tell us.
  3. You can see a test game
    We leave a permanent lobby open. Multiplayer, local network, and it should be listed.
  4. Nova track only: Nova builds workers
    Start an offline game against Nova as Terran. If it just sits there, the Nova pack did not install correctly.

When something goes wrong

I cannot see the host game in the list

Check ZeroTier shows the network as OK and not pending. Then check Windows Firewall is allowing the game, because it usually asks once on the first launch and people click no. Restart the game after either fix.

Anything else

Tell us what you are seeing and we will work through it with you, usually the same night. Nobody has ever been the first person to hit a given problem.
