First time writing a review, but then again no game I've bought from here short of the Tomb Raider series has been this broken and unplayable. This is entirely the fault of WB Games Montreal, and not GOG. Fresh off of Arkham Asylum and Arkham City, I was really looking forward to the next installment. Unfortunately, the bugs and glitches I've encountered have stopped me from even reaching the end of the game. The small glitches were annoying, like the enemy's AI suddenly breaking and leaving them all standing stone still until taken down. Having to exit out and re-enter the game because the game suddenly stopped recognizing grapple points got old fast. Having enemies glitch into walls was funny, up until it was an enemy I NEEDED to interrogate, then it wasn't funny at all. Having Deadshot roll into a wall and softlock the game wasn't funny either. But what has ruined the game for me, is the unfixed(and never will be fixed since WB Games Montreal already declared the game bug-free and not getting anymore patches) glitch with the My Alibi club. For those that don't know, going into the back room of the club to get the Data Pack back there makes textures disappear, and your save file will be locked in an endless fall in darkness once you try to re-load your save to fix the issue. 80-90% of the way through the game, and you get stuck in an unwinnable state, and your save file is useless after that. There is no fix, the only way to deal with it is to NEVER go there and do that side mission, or complete the Data Pack. Nice work WB Games Montreal. Don't buy this entry in the series, and I can't recommend buying anything developed by WB Games Montreal if this is the level of quality they offer. I regret buying this game, don't make the same mistake. Incompetent devs should not be rewarded.
