Yeah, it's sad that Hooligart have lied again:
"The rotation of modes has become more dense - 1 day Bosses, 2 days Colosseum, without pauses"
Perhaps they're finally getting ready to launch the Pit,
or adding a way to power-up the toys without having to pay.
Or any one of the bullshit promises that they've been lying about for years.
Most probably, none of the ideas above. Don't hold your breath!!
