Retro gaming would seem to espouse substance over style, but not in this case. The Developer, Puppy Games, made Titan Attacks reminiscent of older space shooters, but nobody ever had it so good in the 80's. Lasers and bombs leave light trails behind, and even the pixellated explosions and bomb blasts are full of color. The neatest thing, for anyone who has tried emulation on for size, is how well Titan Attacks runs without any special video tweaks. The only decision to make is whether to run windowed or full screen.
The music is nice and dramatic, and sound effects are cool without being exact samples of any actual classic game. Especially nice are the little screams of escaping aliens when you drill them with a well-placed laser beam. The little green goo explosions are pretty nice, also...
