Marvel is offering up 700 free digital first issue editions of comic books from across its entire history—so you can get your hands on everything from Spider-Man to the Avengers, plus plenty more obscure stuff in between, gratis.
The promotion kicked off yesterday and will run until 11PM ET on Tuesday. Until then, you can download titles through either Marvel's official comics app or its web-based digital comics shop. The website is, perhaps understandably, slightly slow right now—but other than that, what are you waiting for? [Marvel via Kotaku]
