Cycle 4.5.X was eagerly awaited by custom mode players because of its main addition: the teleportation. For the first time ever, it was possible to attack XANA directly by teleporting the lyoko warriors in replika factories and thus destroying the virtual worlds of the virus.
This new gameplay mechanic introduces a brand new battle system using teleportation points instead of health points and action points. Two new windows have been added to the Supercomputer's interface to guide and to control the characters in replika factories, the 'Replika Factory Plan' and the 'Replika Factory Map'. New musics were added for this new type of mission.
To defend his factories, XANA can now activate replika towers to teleport kankrelats. Monsters in the virtual worlds can attack the Skidbladnir outside of his garage, trying to destroy it and stop the offensive from the lyoko warriors. A new type of monster has been added for the first time in the game: the replika factories monsters.
Some tweaks have been made concerning the story mode. The second part of the old chapter 1 became chapter 2. The late chapter 2 became chapter 3 completely remastered. Finally, all chapters (prologue included) are playable in this cycle (which wasn't the case before).
This cycle was tested by some players about one month before its release at the Cartoon Fair, a french convention dedicated to cartoons from the 2000s.
