I am surprised at the negative reviews of this game. I have been playing this for years using MAME and always struggled with the mouse/keyboard combo, so to have this on XBL and working with a single controller is excellent.
I would have liked to have seen more improved graphics as well as the ability to play on either side online, but for 400 points, just having this as a workable game again is worth it for me. Maybe it's because I grew up with the game.. I could see how others might view this as a very dated and unchallenging game.
There were reviews in the 4/10 range.. I would give it a 7/10.
Only problems I have with this game are that the aiming reticle moves to slow and should have adjustable sensitivity. The other problem is that the online play is extremely laggy; almost unplayable.
Love this game though, played it all the time in the arcades back in the old days, ahhh memories.....
