And the event is done. I got all 24 medals, I was very lucky in the last stage since I got all the random routes I needed with one squad to reach the uppermost boss, so I 3 medal'd it at first try. Only the first one gave me a little trouble because I didn't adjust my squads' speed, so my first one would reach the flag before the others would reach the enemy. Second stage was really weird with the random routes, my squads were stuck in the centre of the map making loops for quite a lot of rounds.

As for the last stage, the bosses weren't that hard I completed it with my main squad being at 46k power, second and fourth at 26k and my third at 29k. Also I loved the music for the last boss, Ancient Threat. I turned it to maximum as I battled it.

The stages dropped gifts like in the first phase, so I assume ?-4 still is the best place to farm them right?
