    • Mate your server used to play with full of bots, from where you find that revenue? 
    • IAM one of customers of this project. Have anti cheat, have user panel everything is working. Blocking adrenaline trashy plans without any problems.  So just GL for all lin2 project. I get support every time I need it. 
    • Convert package formats from Old to New in one click Create new packages of any format Lineage2Ver121 encryption (included in the package) Safe editing: work in a copy, full undo history (Ctrl+Z / Ctrl+Shift+Z), single "Save" button System integration Open .utx / .ugx files with a single click in Explorer (associations are registered during installation) One example: open a file and add its tab to an existing window Multilingual interface (EN, RU, UK, ES, PT, EL, KO, VI, ZH) — the language is picked up from the system Supported formats Packages: UTX, UGX Textures: RGBA8, DXT1, DXT3, DXT5, G16, P8 Resources: GFX (Scaleform) Requirements Windows. Java is not required—it's included in the build. Installation Run La2Tools-3.0.2.exe—the installer will create shortcuts and register related files. Alternatively, use the portable version. https://la2.tools/files/La2Tools_3.0.3_setup.exe   https://la2.tools/files/La2Tools_3.0.3_portable.zip  - Portable version  
    • WHEN SAYING “YES” IS A MISTAKE Not every project is worth taking on, even if the client is ready to pay. Sometimes refusing isn’t about losing money — it’s about protecting your reputation and time. Over the years, we’ve learned to quickly spot the cases that are almost guaranteed to turn into problems. Here are the most common situations where we turn down work: ▪ The client wants it “like everyone else’s,” but with lots of custom changes and on a minimal budget ▪ There are no proper source materials, yet the deadlines are already burning and everything is needed “yesterday” ▪ Constant changes to requirements after the work has already started ▪ A task with a very low chance of success, but very high expectations ▪ The client isn’t willing to discuss the process and sees us as just an executor - A good result almost always starts when both sides have an honest understanding of the risks and real possibilities of the project. If you’re currently discussing a project and unsure whether to move forward — write to us. We’ll honestly and directly tell you whether it’s worth taking on or if it’s better to look for another solution. › TG: @mustang_service_ms ( https:// t.me/ mustang_service_ms ) › Channel: Mustang Service ( https:// t.me/ +JPpJCETg-xM1NjNl ) #documents #drawing #photoshop #refuse #cases
    • The price reflects the value of the project, not just the source files. This is a complete, production-ready server that has already proven itself over the course of a full year, with a loyal player base and no major issues requiring ongoing development. To put it into perspective, the asking price is approximately what the server generated in one year. You're not buying an unfinished pack that still needs months of work, you're buying a polished, fully tested, revenue-proven project that's ready to go online. Considering that, I believe €35000 is a fair price.
