A modder has released a trailer for a Metal Gear Solid mod which brings two-player co-op to the PS1 stealth classic.
A recent trend I've loved in the modding scene is players going back to classic games and implementing multiplayer into titles that were never designed for it. They are so prevalent there's an entire website dedicated to them. Super Mario 64 is one of the most famous examples – very recently, its sequel Super Mario Sunshine also had a mod released – as are the mods that allow full-blown co-op in FromSoftware games as opposed to certain sections. But one game I never expected this phenomenon to reach was Metal Gear Solid.
