Bought the game immediately on release day and played it quite some time. Tactical Challenges 1 - 5 were quite challenging but 6... well, it made me rage and feel damn hopeless like not so many games before... So i came to the point where i said FUCK IT TC 6 CANT BE DONE. At that time only a handful people had completed this game and there was only 1 video of an asian guy who beat it(and he got pretty lucky @ wave 5...).
I gave up.
...Now, over a year later, i think i can do that shit. It will take some time to get a feel of the game again but THIS TIME i won't retreat... Starting tomorrow or maybe a bit later.
Wish me luck guys.
