Tampermonkey userscript for estimating the likely slowest unit in an incoming Grepolis attack.
It is mainly useful for quickly spotting whether an attack may contain a colonization ship and, in some cases, land catapults. The script provides an estimate, not a guaranteed unit composition.
Beta. The script is already usable, but it still has important limitations and should be treated as a practical helper rather than a perfect detector.
- Analyzes incoming attack timing
- Estimates the slowest unit in the command
- Focuses especially on colonization ship detection
- Can also be useful for selected catapult cases on the same island
- Mythical units are not fully supported
- Speed bonuses and special effects are not fully accounted for
- Results are heuristic and may be inaccurate outside its main use cases
Install directly with Tampermonkey:
Manual installation:
- Install Tampermonkey.
- Open the raw script file at Scripts/CSDetector/src/myscript.user.js.
- Create a new Tampermonkey script, paste the contents, and save it.
- Open Grepolis as usual after installing the script
- Inspect incoming attacks from the target town view
- Open a command window and review the estimated slowest unit shown by the script
- Open incoming attacks through the active commands icon for the town, not the administrator overview.
- Open the attack window and inspect the predicted slowest unit.
- Browser with Tampermonkey support
- Tampermonkey
