The package did not grant you upgrades all the way to maxed cc 20 base, and if it does, that still does not hold any relevance as we are in Arc 1 still and we have a month at the least to go to Arc 2 and the current Arc 1 units can easily do any of the 3 bases free repair, and as a low level player, the weapons lab should not be on his list as PVP is only manageable with a high end base and units.
And even then, Arc 2 units can probably go to lvl 10 with the current levels he has which is more than managable.
Nothing i said is bs nor remotely close, but you need to understand that if you are not able to beat a base then you are not good enough or well equipped to take it on and should go after a lower difficulty target until you have what it takes to do it.
Git gud basically as Drake has said yesterday
