CoD mobile is good... when played in an Android emulator on PC. It's basically CoD: Greatest Hits, and it's way better than Black Ops 6 (or any console/PC CoD, for that matter). All the best maps from the old games are there. Takes me back to the days of MW1 & 2 on the XBOX 360.
The only issues is that it takes some tweaking and the right emulator (Gameloop) to get a steady 120+ FPS, and it can take dozens of matches before game starts pairing you with other mouse and keyboard players (instead of just bots or controller/touchscreen users), but once you've established your rank, it becomes ton of fun cause you're not just destroying everyone you match against. It becomes a legit challenge.
