Serious Sam 4: Planet Badass might have recently been delayed to September 24th but that just so Croteam can put the finishing touches on the new Popemobile. See, in the new game Sam visits the Vatican, and when aliens attack, a friendly Italian granny directs Sam to commandeer the Popemobile, which is basically a Metal Gear. You fight a giant 3-eyed tentacle monster. In the Popemobile. Yeah...just watch the trailer.
Croteam, you had my attention. Now you have my pre-order.
