Atari's legal team is getting quite a workout lately, just yesterday they demanded that 4 more App Store games be removed with more likely to come. It was not long ago that TiPb reported that two other notables were forcefully removed, Tris and PhoneSaber.
The 4 apps kicking the bucket this time around due to "infringements against the pong and breakout copyrights" are as follows (iTunes links): BreakClassic, BreakTouch 3D, Super Pong 2, and 3D Vector Pong.
As of today, all 4 of these apps are still available via the App Store. So get them while you can!
