One of the things that fascinates me in the PC is the amount of people who dedicate their time to modify some games, giving sensational productions and so absurdly extending the life of the securities serving as a base.
The most amazing is that not content with changing recently launched and / or who are still highlighted games, some of these modders to continue creating good old games, games that were roped there in the early 90s, as Wolfenstein 3D.
A beautiful example of this is the Batman: No Man's Land, free modification that can be obtained here and that will transform the classic FPS is a great adventure estralada the Dark Knights.
Continuation of another mod, Batman vs. Bane, the game will visit a part of Gotham City that was destroyed by an earthquake, with the main objective to rescue some hostages and of course, defeat groups of bandits started to terrorize the site.
Two information that probably you please and will make access easier game is that in addition to work without the need to have the Wolfenstein 3D, Batman: No Man's Land was also optimized to run on newer versions of Windows, so there are no excuses not to give a chance to this modification.
PS: If you want to know other interesting creations that use the engine of Wolfenstein 3D, just take a look at this list.
