War Thunder is a server-authoritative game. This means that while your computer displays your "Silver Lions" or "Golden Eagles," the actual number is stored on Gaijin's servers. If you use Cheat Engine to change "1,000" to "999,999" on your screen, the change is purely visual. The moment you try to buy something, the server checks its own database, sees you only have 1,000, and the transaction fails.
Armor penetration and damage calculations happen server-side. war thunder v143749 engrus l cheat engine best
