Hey guys, I need some advice on how to finally beat that last XP challenge base. I want to do it at least once during the event. So far 3 tries 3 fails and only because of the super stron aircraft in this base. I have ono idea what those choppers are because I've been away for years bt they kill everything very fast and take almost no damage.
Useful units I have are:
15 Aggressors (could build 2 more)
1 Twinblade (could build 2 more)
I have 2x Helios in build queue and little over 600k Event XP so I could buy some more harpies or something else.
So far Harpies and even Absolvers weren't enough to kill the choppers, maybe because they were already damaged too much by the other units. What do you think which unit I possess ist best against them? I'm thinking about trying Helios on them but I would have to coin one for it to be insta-built and I don't really want to atm.
Other problem is I'm also running out of time. By the time everything but the choppers is down I mostly have maybe 1 minute left, sometimes a bit more. So, any advice?
