not gonna lie but in the game there is already takedown option but i disabled it in the lastest update cz its glitchy i will update it soon, and there is already stealth mission in the game called CQB
be patient there the release time is unsure, the game is still under development, however im glad that the game is getting more fans, i got a new update for you guys with interesting horror story mode, and new functions, and easter eggs and new weapons and new npcs and missions like cqb's and parkour maps
