Well that was simple enough..  Turns out objects weren’t quite drawing right because I forgot I had applied a modifier to change the pace of the different size tanks.. Well this modifier affects where the objects are positioned as well.. doh! Turns out it was simple, just something a tired mind can overlook! Now I just have to add the particle system to the class and then modify it so it adds / updates and moves the emitters.. and done with this one!

Then on to build the routines to drop the score items and health / energy items.. =)
