MegaCase is a new CS2 case opening website launched in the summer of 2026. Unlike most traditional case opening platforms, MegaCase introduces a unique feature that lets players create their own custom CS2 cases. You can choose the case price, adjust the odds of receiving high-tier skins, and instantly open the case you've designed. Besides Counter-Strike 2, the platform also supports custom cases for Rust and Dota 2, making it one of the most innovative case sites available.
Both new and existing users can activate a MegaCase promo code when making a deposit. Every code listed below provides an extra +2% deposit bonus, which is currently the highest bonus available on the platform.

Simply enter any of the promo codes above before completing your deposit, and the 2% bonus will be added to your account automatically.
MegaCase does not currently offer a free starting balance or no-deposit bonus. However, you can claim an additional 2% on every deposit by using one of the working MegaCase promo codes. This gives you more balance to create custom cases and open additional CS2 skins without spending extra money.
The biggest advantage of MegaCase is its Custom Case Creator. Instead of opening pre-made cases, you can build your own by selecting the opening price and adjusting the drop rates for valuable skins. This unique system allows players to experiment with different risk levels and create personalized case-opening strategies based on their budget.
For our review, we started with a balance of 1,000 RUB. After a series of successful openings and careful bankroll management, we increased our balance to approximately 10,000 RUB. While results like these are never guaranteed and always depend on luck, they demonstrate the potential of MegaCase's custom case system when a favorable streak occurs.
