Five out of five stars.
⭐⭐⭐⭐⭐
Quality & Functionality. It's all there. I personally don't use anything other than ESP, but everything else works great. Aimbot, unlimited ammo... everything you'll ever want is there. The NexGen team (and the community around it) are always testing and sharing experiences to make things better. What else could you want?!!
Support & Updates. The NexGen team is very diligent when it comes to updates and customer support. Generally I get a reply to a question within minutes. Sometimes it takes a couple of hours -- which is completely understandable, because we all need to sleep sometimes (and have real-world lives). Updates for SCUM come quickly and are well tested (with constant progress updates).
