AS a huge fan of Metal Slug, I am excited that Metal Slug is coming on PSN.
 
But hey, That's not really a big news. 
 
You bet it's not.
 
The big news is that it will support Co-Op play!
 
I think it has already been done on XBOX but I don't have it so whatever. 
 
I'm just happy it's finally coming on a platform that I have and I am very very excited!!
 
There are also other good Neo Geo games coming out on PSN such as Samurai Warriors and King of Fighters 94 (That's right! We go Old Shcool!)
 
Here is the link about the details.

XBL has Metal Slug 3 aka the best Metal Slug. And also all of SNKs games have terrible online so don't get too excited.

That'd be cool if we got the same SNK fighters that XBLA has.
