It has become a clickfest on upgrades for me. by the time I am done clicking 100 upgrades per technology i have to click another 100 on the sponsors and then back again.
Can we have a buy all upgrades instead of having to click like 40 times per technology at the upper levels. At car 15 tech 13 and adding to the lag its slow
bug. if you did not buy the x4 multiplier upgrade over 200 and bought the extra levels first, you don't get the x4 effect for the levels you already bought
the only strategy i found that works is max mines and rockets. a max mine upgrade can kill a tank, medic, commander or the pesky blue guy that freezes your tower. keep airstrikes and tower for the above.
thanks aloe, I will check that
