After watching the last half an hour of Matrix 3 movie, I noticed its very similar to the 4th vertical mode 7 stage of Axelay, where you fly over the city with the cool lights & then you fight that huge orange colored witches-cone-hat, Mecha boss thing. It reminds me a lot of the last scene in Matrix 3 where they fly over the machines city & then they head towards the mountains & a similar Mecha (Sentinel) rises over the mountains & starts firing at them the same explosive missiles as the Axelay Boss!
Neo reflects them with his powers from his hand though...
Is this a coincidence or the animators of Matrix 3 were playing Axelay in their childhood?
By the way the ending in Matrix 3 sucked. Axelay was better!
Also if you complete Axelay in Hard mode for the second time it shows this:
"See you again at: Axelay 2"!?
It's a pity KONAMI Never made this!
