We're not done with 2009 just yet, but adventure gamers should pull out their 2010 calendars a little early to mark down the impressive lineup now unveiled by Mamba Games for the UK in the first half of the new year.

You can see each game listed in our usual Release Dates calendar, of course, but when an announcement is full of this many highly-anticipated games, it's worth an extra notice. Headlining the list is Jane Jensen's long-awaited Gray Matter, now scheduled for release on May 21st. Helping fill the wait until then will be Ghost Pirates of Vooju Island (February 19th) and Black Mirror 2 (April 30th). There's more after that as well, as 15 Days is set for June 25th.

That's just the games never yet released, of course. Mamba, through its adventure-based Odyssia brand, is also releasing several other games for the first time in the UK. Along with the first retail version of Machinarium on March 5th, gamers who missed out on the earlier North American releases can look forward to the arrival of Memento Mori on February 12th and Mata Hari on March 26th.

Although official, bear in mind that all release dates are subject to change. The fact that the publisher is narrowing on on specific targets can only be good news for gamers, however, so 2010 is already shaping up to be a very promising year.
