Maps are very simple in design, but most still look surprisingly good. Cinematics also use the in-game graphics engine. Going into this review I wasn't sure what to expect from this game's graphics, but I was definitely surprised with the result. Another surprisingly strong feature of Serious Sam is its audio. It isn't anywhere near as good as that of Undying, but it is more than I was expecting to find.
Sound effects are clear and fairly realistic.
Weapons sound about as much as you would expect them to. Creatures sounds are also well done although there isn't much variety to be found. For instance, all humanoids give a Doom-like grunt as they spot you. Both types of scorpions use the same sounds as do all species of frogs. These guys gallop around you like horses and then leap at you when they get close enough.
