Unlike other apps that drown you in ads, this arcade port just makes you purchase the game. In my opinion this is better. And the port is phenomenal. Not only is gameplay phenomenal and accurate to the arcade, but the settings allow players to re-create the experience of the arcade cabinet version they grew up with. You can seamlessly change between monotone, color, the cellophane overlay, and the original moon backdrop. You can also choose between a joystick or buttons. It even has tilt control options! I do have two small issues with the app. Using the moon backdrop option, the UFO is incorrectly colored white instead of red. Secondly, the menu could use a slight update. It is obvious that this app is a relic from the App Stores early days. That being said, they have updated the app to keep it functional and full screen unlike some older apps. I would definitely recommend this.

I haven't played this game on my iPhone for quite a while, so I'm not familiar with the updates that people are complaining about. I just now played it for the first time in a long time, and I found it extremely enjoyable and I have no idea why people are complaining about the updates. I found it to be flawless and reminded me of the time when I worked as a dishwasher at a bar that had this game in 1981 and we would drill a hole in a quarter and used thin fishing line to get free games. Personally, I highly recommend this app.

Near-perfect arcade emulation of the original game with bonus artwork and tips as well as challenging achievements. No ads, in-app purchases, or any other junk bogging it down. Only “complaint” is that the gyroscope and slide control options are useless except for the achievements for trying them out; I doubt anyone actually prefers them. Other developers should take notes from this app.

It’s nice to see original game developers port their own games over to iOS. Space Invaders seems to work flawlessly. It behaves exactly as I remember the old arcade versions behaving (not harder or easier). Back in the day, I spent MANY quarters in the arcade on this and many hours on the Atari 2600 playing this. This port looks good, sounds right, and it’s loads of fun. Worth the $4 to me.
