Roblox / Tower Defense Simulator / Automation
Ultimate Macro: The New Era is a free, open-source automation tool for Roblox Tower Defense Simulator. Play a run yourself once and it saves every placement, upgrade, ability and target change as a strategy file — then replays that run, rotates between strategies and recovers from disconnects while you are away.
The Ultimate Macro window, running on Windows.
What it does
Ultimate Macro is not a mouse recorder. It reads TDS menus, tower state and match flow through image detection and OCR, so each phase of a run is handled on its own terms.
Play the run yourself once. Every action becomes a reusable .strat
file.
Loop a strategy for hours, or rotate between two of them.
.strat downloads in-appLosses, lag and disconnects are handled instead of ending the session.
Watch a session you are not sitting in front of.
Everything runs locally as an AutoHotkey script on your own machine. Nothing is injected into Roblox and no account is needed — it reaches the network only to fetch community strategies and to talk to the Discord webhook and remote control you set up yourself.
Before you start
Ultimate Macro reads the game the way you do — through image detection and OCR. These are the settings that matter most. The macro lists the full set the first time you run it, and the guide explains what each one is for.
Questions
Setup and troubleshooting live in the guide. These are the ones people ask before downloading.
Yes to both. Ultimate Macro is released under the GPL-3.0 licence and the whole project is on GitHub, including every release. There is nothing to pay for and no account to create.
No. Open the Record tab, set the map and mode, press Start Recording and play a run
normally — the macro writes the .strat file for you. You
can also browse and download community-made .strat files
from inside the macro, shared through the Discord.
It is an AutoHotkey v2 script that moves your mouse, presses keys and reads your screen with image detection and OCR. It does not inject code into Roblox or modify the game. It reaches the network only to fetch community strategies and to talk to the Discord webhook and remote control you configure yourself. Antivirus software sometimes flags automation scripts in general — the full source is public if you want to check it.
A 1920×1080 Windows display resolution is required — that is what the macro's image detection is built around — with Windows display scaling set to 100%. Note that this is your Windows resolution, not a setting inside Roblox.
No. The macro drives the real mouse and keyboard and needs the Roblox window where it left it, so the machine is busy for the whole session. Set up a Discord webhook if you want to watch progress from your phone instead.
Ultimate Macro was started on 30 March 2026 by Darksen. The New Era is the continuation of that project, maintained by a new team. Full credits are further down this page.
No. Ultimate Macro is an independent, community-built project. It is not affiliated with, endorsed by or connected to Roblox Corporation or Paradoxum Games.
