Just spotted that DOOM is available in BlackBerry App World, for free.  I’m hoping this stays there, but just in case it doesn’t head over and download your copy free before RIM pulls it out (if that’s the case).  For those unaware, DOOM is a classic walkaround shooting game, very popular on older PCs throu MS-DOS even.  Memories.  The developer does list some known problems with it:

• Multitouch implementation is far from perfect, freelook and movement/action buttons must be touched in a certain order to work together.
• The buttons could stuck in certain situations.
• Only the shareware episode is playable.
• Very minor sound stuttering.
