well i still had 11m when i woke up today so spent the whole day raiding to get up to 22m (35% discount) for my second level 2 nano which is the most money i have saved up without selling anything , i have max allies so there is not as many easy targets but i attacked players with low stats and average buildings like level 3 oar mines ect and players with around two thirds of my stats for bigger targets like level 3 oil rigs ect , to get the 11m these are the units i lost in battle :
13 snipers ,30 flamethrowers,1 heavy gunner,2 hardened marines,18 commandos,16 bradleys ,1 stryker,1 expert attack drone,1 rocket truck,15 warthogs,1 sea hawk,5 chinooks,2 spectre,6 inflatables,2 frigates,2 combat boats,6 submarines,1 amphibious hover craft,3 stealth frigates and 2 mine launchers + loot items which i didn't keep a record of !
at least i have the upgrade and the units i can replace .
just thoght i would let the lower free players know what they can expect to have to do to get big upgrades , i hit two missions to get the last 500k to save waiting the 10minuites for payout buildings as i had enough of the fear from attack . there is only a few players arround who could have attacked as i have built my stats up in last month or two which is why i did it without selling . i know there are free players who can top this and other methods but just wanted to do a post . i am level 93 .
