The Incredible Adventures of Van Helsing II was originally slated to hit Steam on April 17, but has now been pushed back to May 22 "due to Monster Invasion." Okay, so that's obviously not the real reason – the real reason is that developer NeocoreGames wants to take an extra month to polish the game, ensuring the sequel is superior to the first game in every way. The date will also mark the one year anniversary of the first game's release, so it only seemed natural.
The silver lining – aside from extra polish – is that you now have an extra month to nab some pre-order bonuses, while still getting immediate access to the Closed Beta. Speaking of the Closed Beta, Neocore published two screenshots from it, which can be seen below.
