The official Arc System Works website for DNF Duel went over the Switch version’s features. The Q&A section on the product page for that iteration confirmed that there will be no crossplay compatibility. In addition, this version of the game will not feature rollback netcode like the others. It also noted the Dungeon Fighter Online bonus that comes with physical copy pre-orders. [Thanks, Resetera!]
If you are playing DNF Duel on the Switch, then you will only be fighting people who also own that version. The Q&A noted crossplay is limited to PlayStation platforms. So someone on a PS4 or PS5 could play someone on a PS4 or PS5. The PC version also lacks crossplay.
As for the DNF Duel Switch netcode, it is delay-based. All other versions available now use rollback netcode.
As for the Dungeon Fighter Online bonuses, here’s what you get with the physical copy.
- 1 DNF Duel Celebration Coin
- 1 DNF Duel Title
- 1 Inventory Expansion Ticket
- 1 The Lost Warrior Creature in one of two colors.
- 10 Life Tokens
- 15 Day Master Contract Package
- 15 Day Neo Premium Contract
DNF Duel will come to the Nintendo Switch on April 20, 2023. It is available for the PS4, PS5, and PC. The Season Pass DLC characters will begin appearing in Summer 2023 with Spectre.
