Immediately after that, we were treated to a scene in which Kratos works his magic on Helios, the sun god whom he rescued in Chains of Olympus. And note that when we say “works his magic,” we mean he straddled the god from behind, grabbed his head with both hands and – in a brutal, multi-stage button-mashing sequence that focused closely on Helios’ agonized face – tore Helios’ head right the hell off. It wasn’t just a clean rip, either, as the skin stretched and tore, revealing muscles and tendons underneath that snapped loose individually as the god screamed out his final breath.
And hey, look at that! It wasn’t just for show, as Helios’ head is a magical item that can reveal hidden passageways, light darkened areas and stun light-sensitive enemies.
The enemies have a few tricks up their undead sleeves as well. Certain shield-bearing enemies will form phalanxes to defend against Kratos, as a few undead soldiers did to protect Helios from Kratos’ head-ripping presence. And remember that centaur we mentioned earlier, the one who got gutted? He was a commander, meaning that when he’s around, other enemies get smarter and work together to attack you. Gut him, and they’ll be dumb brutes again.
Probably one of the coolest new creatures to be shown during the preview was the chimera, which is interesting not so much for what it is, but for what it does. Like the mythical chimera, this one is a creature that’s part goat and part lion, with a snake for a tail, and you’ll need to fight it in three separate stages. First, it’ll attack on four legs, using the snake-tail as its main attack. Once the tail is severed, it’ll walk erect in the “lion stage,” and when that’s defeated, it’ll charge you with the goat head, at which point you’ll be able to break off its horns and stab it to death with them.
