What are some sick 16-bit Co-op games?

[masschamber]

and you might want to get some neo geo games,
some really good neo geo co-ops
Nam '75, tough as nails but a good time none the less
Blazing Star and Prehistoric Isle, easy to play, fun to look at horizontal shooters
Andro Dunos, Last Resort, not as pretty and harder but still good horizontal shooters
View Point, someone had the bright idea that co-op shouldn't be the default setting in this one, turn it on in the soft dip screen
Shock Troopers 1 and 2, over head run and guns, multiple paths and a lot of characters
Top Hunter and Spin master, 2 player action-platformers
Metal Slug 1-3 and x, obviously
Sengoku 3, probably the best beat'em up ever, 6 different characters each with their own special moves, a deep and interesting combo system, and it is the best looking beat em up on the system, stay away from all other neo geo beat em ups, they are all ugly clunky and dull
Zupapa and Nightmare in the dark, bubble bobble like games
Ninja Commando and Ghost Pilots fun overhead shoot'em ups,
Aero Fighters 2,3 and Stikers 1945 x, easier and pretty over head shoot'em ups
Baseball stars 2, super baseball 2020, Street hoop, and Neo-turf masters, fast paced arcade style sport games
