IMO the best Web-Slinging Simulator available on Steam at the moment...
NUFF' SAID !
As much as this game tries to be a mix of the good old Spider-Man2 and Batman Arkhams without ever reaching the level of any, it's still a pretty fun Spidey game.
Yes it's kinda buggy (no pun...), yes your web will always stick to something about 20 meters above the highest point available (but quite frankly I do'nt really need realism in a COMICS game, and furthermore this stuff happens all the time in the comics), and yes the levels are linear with a combat/stealth system being an inferior copy of Batman Arkhams.
But once you get out in the Big Apple and start fighting crime, collecting comics and stuff, or just websling around it's pretty damn fun.
