Select a few units and move them northwest where a Tan base is located. Destroy 
it if desired. Go to the left opening of the thing that is almost blocking the
way to way where the "X" is on the map. You should find a weapon boost power-up.
Get it, if needed. While your units are standing slightly in front of those tan 
pillow things where you got the power-up, you may be able to see a few school 
binders stacked up with a lunch box on top. You may need to get the view higher.
Once you see it, you will see a picture of the Green and Tan army men soldiers 
fighting each other in Army Men RTS.
