'Mega Tower Challenge' is an 'Only Up!' type mod for Sonic Frontiers, which replaces the Ouranos Island Battle Rush with a new Time Trial consisting of all 11 Towers from Rhea Island and The Final Horizon. The towers have been stacked on top of each other to create one massive platforming challenge.

The mod also features a Music, Weather and Time of Day customizer, if you want to personalize your playthrough (accessible via HedgeModManager).

To start the climb, select the 'Mega-Tower Challenge' option on the Title Screen and choose your save file. If the option doesn't appear, then replace your Battle Rush save with the one in the Extra Downloads section (instructions included in zip).

Make sure to have Quick Cyloop unlocked on your save file and to read all the hints at the start of your run!

Note: this mod disables the Power Boost due to the game always starting you off with MAX Rings.
