[quote name='Skexis']Well, not exactly. That's murky water, kinda like having mame roms on your hard drive, but basically you don't have much to worry about.
I played it for a bit, but the whole respawning zombies thing kinda turned me off. Cool atmosphere, though.[/QUOTE]
This isn't the type of ROMs that the underdogs usually distribute. This is the publisher/developer (Looking Glass, IIRC) actually agreeing to place the work into the public domain for free distribution. So no murkiness whatsoever.
