This base has an investment of almost 4 years playing the game (4 to 6 hours daily) plus $2K USD over all that time. Do the math! Base was fully maxed 3 months ago when I quit the game. So it may be somewhat behind but with the amount of gold base can easily be maxed again anytime. Just the 1.6 million gold bought in Store offers would cost you $1,200 USD. All FOB units are maxed. Helicopter FOB Lvl 13, Light Vehicle FOB Lvl 12 and Heavy Vehicle FOB Lvl 12. Latest Units Maxed: MH-5 Python. Titanus up to Level 10. All Tech slots maxed.
