I was not aware that the assault rifle would only be available thru playing an extra region. Now I have cleared region 16 but do not have access to buy the assault rifle. I have spent around 20 million on the rifle and upgrades and shotgun with upgrades.
I agree with the post about very little reward for the gold spent. Over 400 gold for a crossbow and around 100 platinum. Now finished part 2 and no reward.
I have finished part 1 & 2. Spent over 400 glu credits. Recieved one crossbow and received approx. 100 platinum credits. I may stop playing the specials.
