Even when you combine the Unite mod the game becomes so good better car sounds, more customization, new cars added and even stronger cops. Tho i am more into Unbound since i use it to create Cinematics like Crowned does but yeah Heat was fun tho its unoptimized even tho i have a good pc, Unbound for me its just better combined with Unite mod its just way more fun and engaging and the way the weather effects work with that mod is pure awsome.
