I must apologize for the rather misleading title. While Serious Sam HD: The Second Encounter is indeed coming to Xbox Live Arcade on the 22nd of next month, using the phrase "headed" was probably a poor choice. Why? Well, because of the headless, yet still screaming bomb-carrying berserkers, that's why! They aren't really "headed" anywhere, are they?
Ugh, even I have to groan at the lameness of that joke. It's a good thing Serious Sam himself is coming to spew some one-liners for us, isn't it? Perhaps his quick wit will evaporate your memories of the poor comedic stylings of this editor.
