We'd been talking about this a lot over at TestYourMight.com but noticed it's not been reported on here; it's been revealed that if you enter a secret code when the meteor flies across the sky of the Towers of Time, you unlock a hidden tower that will reward you with one random Kombat League skin (including the present season) of whichever character you fight against.

The meteor flies across the sky every two hours and 10 minutes, I'm in Britain so for me it flies over at 10 minutes past every even numbered hour on Greenwich Mean Time (check a world clock to see whether yours will fly over on even or odd numbers by using that as a reference point). So for example, my meteor will fly over at 10:10am, 12:10pm, 14:10pm, 16:10pm etc.

When the meteor flies over you need to enter the following on the D-pad (you'll only have a few seconds to do so):

Left, up, left, right, left, up, up

(you'll notice the order of the code is actually a tribute to the classic ABACABB blood code)

At which point it'll advise you a hidden tower has been unlocked. Be warned: the towers are expensive to open using the in-game currencies of coins, hearts and souls; your opponent will be armed to the teeth with cheap assists, so make sure you're packing your own to combat them; and do not leave the ToTs tower selection screen, it will disappear instantly if you return to the other menus. They will be up for an hour and once opened you can replay them repeatedly to unlock some KL gear for the character you're playing as.

Have fun finding those KL skins of seasons-past that you may have missed :)
