En van je 123 Oktoberrrrr <| sep |> I think it ' s still possible to clear the last map with only one hero , but it would be difficult . You ' d have to use a lot of support items and unless you have been collecting them for awhile you ' d have to use gems to get more . You don ' t have to clear it if you don ' t want to . The Tower Mods are completely random , which really does suck . There is no rhyme or reason behind what you get . 5 of my 6 purple mods aren ' t good 2 exoskeleton , 2 % infantry cost , and 1 laser turn rate . A lot of my blue mods are better than my purple ' s . That ' s the stupid part about random mods . You can only get Tower Mods during these events . This is the third event that has given out Tower Mods as rewards . I recomend playing through Tier 9 for a purple mod at a minimum and get up through Tier 12 another purple mod if you can . But there ' s still a pretty good chance you won ' t get anything useful This is the downside to free games . they will always push you towards paying money to make it quicker andor easier .
