A nice throwback to titles like Return Fire or Mass Destruction - iBomber Attack is family-friendly glorification of violence and destruction in a Weird War II-setting. Get in your tank, blow Wehrmacht up, upgrade your tank, blow more Wehrmacht up - missions do have various primary and secondary objectives, but it all boils down to "victory through superior firepower" (which is A-okay by me).
The warzones are rendered in a nice 2D style (with some nice attention to detail too) and accompanied by lots of gun- and explosion-sfx which have a decent oomph to them. Probably runs on a Toaster and works very well with a controller.
Once you upgraded your tank enough, you are like a force of nature laying waste to entire cities which is stupidly fun. Not really a clever game by any stretch of the imagination otherwise (and pretty much on the "not challenging"-end of the difficulty-spectrum), but very entertaining if you crave some good old top-down destruction with a twinstick-shooter twist (pretty much everything in a level can be destroyed, rammed, crushed, set on fire... you get the idea!).
