Dead Tide and Transformers Forged to Fight

As if I don't have enough games to play, I started another Android game called Dead Tide:


DIE ZOMBIES! BWAHAHAHA!

And although I slowed down playing Transformers Forged to Fight, I can't help but notice that they ocassionally change the loading screen to replace new bots:


Notice how Motormaster, Prowl, Movie Bumblebee, Ultra Magnus have been replaced by Optimus Primal, G1 Bumblebee, G1 Megatron and Dinobot respectively?
