Note: Progress on the test server does not transfer to the live game.
On the live server, M6 augmentation requires insane grinding. On the test server, you can augment your turret to M7 instantly. Always test the "Micro-Upgrades" (the side branches, like reload speed vs. damage). Often, a specific micro-upgrade that is bugged on the test server becomes the meta for the next three months.
You often need a separate test client or a specific URL (like test.tankionline.com ).
Servers are often only live for a few hours or a weekend to focus testing on a single feature.
: The test server typically opens only during specific "testing phases." Check the official Pro Tanki Discord, Forum, or social media pages for announcements.
