“Humanity is under siege as the full force of Mental’s hordes spread across the world, ravaging what remains of a broken and beaten civilization,” say Croteam. “The last remaining resistance to the invasion is the Earth Defense Force led by Sam ‘Serious’ Stone and his heavily-armed squad of misfit commandos.” In addition to the new cinematic trailer, Croteam have got several other new videos showing off some of Sam the 4th’s new bits, including their big new Legion System wot seems to be the talking point. The prequel will pit Sam against actual hordes, the developers say, “thousands and thousands and hundreds of thousands” of enemies at once, apparently. “Originally we were hoping for 10,000 enemies and now we hit an order of magnitude more,” they say. Suppose that’s a pretty important achievement for a game about gunning down armies of alien baddies. You can find that video and others over on the Serious Sam sale page on Steam, which is where the game’s website currently redirects to. Talk about going all-in, gun hands man. There are some seriously steep discounts on other Serious Sam games over there if you’re looking to catch up on the action. Serious Sam 4 will launch sometime in August on Steam and Google Stadia.
