Project: Eternal is a vanilla-like rundown focuses on F-tier difficulty -- You might expect them much harder than vanilla E-tier levels. Consequently, ultimate team cooperation and effective tactical planning are essential for players to survive every single expedition in this tier.
Some C to E-tier levels are also available, hence there's a chance for players scaled by different skill levels to have some fun in this rundown. C-tier levels incorporate fewer customized features. Deeper levels would be more intend to provide special tweaks and unique playstyle. However, the whole rundown still remains vanilla-like.
PS: Level difficulties are not related to their visual depth shown in rundown page. Tiers are the only matter.
Get troubles beating a level? There's no need to be worried. Custom boosters are provided to limit some op vanilla boosters but still helpful if you encounter difficulties. However, beating a level(complete all objectives) without using boosters will reward you a ://Professional badge, which looks sick af(LocalProgression plugin feature)!
Currently, all levels are no-booster beatable(many tks to everyone who engaged in playtests). A beta version of a new level might be released in ahead of its full release for easier installation during testing phase. Such a pre release will be indicated in change log.
Enjoy the game!
