After having played both Infinite flights, my biggest visual gripe was the effects of the explosions. Booted up Halo 3 today and just realized how sorry they looked in comparison. Halo 3 grenades have actual life and volume to them. Plasma grenades look exactly how you would imagine a ball of plasma violently exploding, and the regular grenades have cool particle and smoke effects in general.
Really just hoping the Halo Infinite ones are placeholders, as they are literally just 2d animated images without any soul or depth to them. Fusion coils, vehicle explosions, rocket explosions, the explosion of the banished fuel depots, all without character. If these aren’t placeholders 343 has some work to do, whether that be before or after launch.
