Latest Japanese PS2 acquisition is Shin Contra
aka Contra : Shattered Soldier
in other regions. It's far more affordable than the Western versions.
What a rip roaring game this is - pure old fashioned side on run and gun with plenty of PS2 fireworks. Brilliant game - there should be more of this sort of thing. Contra really is one of the great games series.
There's Neo Contra for PS2 as well but that's not as good - it's more of a top down view a bit like Cannon Spike. It's a good enough game just not really a proper Contra game.
