Questions

Frequently asked

What you need, what it costs, and how TA Reborn plays.

Before you play

Do I need the original Total Annihilation?

Yes. TA Reborn contains no original game data: no units, maps, art, sound, music or video. It plays the data of your own copy, read in place from its install folder, and never changes it.

The Total Annihilation: Commander Pack on GOG.com, with The Core Contingency and Battle Tactics, is the reference. Steam installs and other copies work too.

How much does it cost?

Nothing. TA Reborn is free and open source, under the GNU General Public License v3. All you need is your own copy of Total Annihilation.

Is it official?

No. TA Reborn is an unofficial fan project, not affiliated with or endorsed by the owners of Total Annihilation. It is a clean-room reimplementation: a new engine, written from scratch in Rust on the community's decades of research into TA's file formats, without the original game's code.

Which computers does it run on?

Windows 10 and 11 on x64, and Windows 11 on ARM64; macOS 13 or later on Intel and Apple Silicon; and Ubuntu 22.04 or later and Arch Linux on x64 and ARM64 (Arch Linux ARM).

Windows has an installer and a portable ZIP, macOS an app ZIP and a disk image, and Linux DEB, Arch and portable packages.

What graphics card do I need?

One with DirectX 12 or Vulkan on Windows, Vulkan on Linux, or Metal on macOS; integrated graphics play on Low. High wants 6 GB of video memory and Ultra 10 GB, and ray tracing a card that traces rays. The launcher itself needs OpenGL 2.0.

The launcher's benchmark is about three minutes of staged battles: it scores your graphics card, processor and memory and recommends the settings that hold 60 frames a second.

Why might my computer warn me about the download?

Builds that are not signed with a paid certificate make Windows and macOS cautious the first time.

On Windows, if SmartScreen says it protected your PC, choose More info, then Run anyway. On macOS, if the app cannot be opened, open System Settings → Privacy & Security and choose Open Anyway. Every release lists SHA-256 checksums to check the files against.

Playing

I have never played Total Annihilation. Where do I start?

With the primer on this site: the Arm and the Core, your Commander, metal and energy, factories and orders. In the game, the tutorial teaches the same in three short guided games on Painted Desert; then play a skirmish against an Easy computer player, then Normal.

Does it still play like TA?

Every unit, map, campaign and sound is TA's own; everything around them is new. The simulation runs at TA's 30 ticks a second and TA's own unit scripts drive the units.

You can keep TA's 1997 interface and its top-down camera (F5), all of TA's controls and chat commands, and its way of moving: the movement rule "As in TA" turns formations off.

Which campaigns can I play?

Every campaign of your install, with TA's own mission scripts: the Arm and the Core, and The Core Contingency's and Battle Tactics' if you have the expansions. Conquest takes a galaxy of TA's worlds system by system, and eight scenarios (Last Stand, King of the Hill, Doomsday Clock and more) each have goals of their own.

Can I play online?

Yes. Multiplayer runs in lockstep over a local network or the internet, with a lobby, spectators, chat, rejoining, and an ally taking over a lost player's army. Skirmishes take up to ten players, with computer players at three levels.

Every game is recorded: seek through it, watch it as a tournament's cast, or export it as a video.

Do mods work?

Yes, and they need no code. The launcher's mod library brings community conversions from ModDB in one click, among them Total Mayhem, TA: Escalation, Talon, Total Battletech and The Final Frontier. Mods load from folders or TA's own archives, later ones over earlier ones.

Every mod is checked in the background against the game without it, with a readable report of anything it breaks. The map editor saves its maps as mods that the skirmish page lists at once.

Can I use a gamepad?

Yes, the Steam Deck's included. Keys can be rebound, orders given with either mouse button, and units drawn in colour-blind colours; the launcher's and the game's Accessibility settings hold the rest.

Which languages does it speak?

Fourteen: English, German, French, Spanish, Italian, Brazilian Portuguese, Polish, Russian, Ukrainian, Turkish, Japanese, Korean, and Simplified and Traditional Chinese.

Where are my saves and settings kept?

On Windows, shared mods, skin packs and downloads live in %APPDATA%\TA Reborn, and each commander profile's settings, saves, replays and progress below profiles\<id>. Screenshots and photos go to Pictures\TA Reborn and videos made from replays to Videos\TA Reborn. Your Total Annihilation install stays as it is.

The project

How is it made?

In Rust, as twelve crates: TA's file formats, a virtual file system over the install and the mods, a deterministic 30 Hz simulation in fixed-point arithmetic with a virtual machine for TA's unit scripts, the computer players, lockstep networking, and a wgpu renderer. Every computer in a game computes the same battle, which is what multiplayer, replays and rewinding stand on.
