I played tw or three years back on a different account. When I played that account there was a map called Solomon Islands. I see it is still listed as a map for the game on the wiki page. This time around on this account, I have yet to play that map. Did they move that map to a specific tier or scenario? Or did they retire the map? I kind of liked that map in coop play. The bots were very predictable on it. While it was frustrating sometimes going around the big islands, the chock points were always target rich.

Anyone know what the deal is with this map?
