One can't help but question the necessity of this port. Dead by Daylight Mobile doesn't really fix anything that was wrong with its original release for consoles and PC, including that game's general lack of terror and creepiness (it's more concerned with grisly competitive action than sending an authentic chill up your spine), as well as its matchmaking issues, which can see players waiting a very long time for a game to begin -- especially if you choose to play as a killer. Plus, it adds several new problems to the mix. For starters, the touch controls can be deeply frustrating, making it difficult to precisely move, target, and interact with objects. There will be moments when even veteran players will feel like they're rookies learning a new interface. And it's an ugly looking game. Bland textures, stiff animations, and a general lack of detail give this mobile port the look of a middling PC game released sometime in the early 2000s.
Admittedly, it's nice that we can download and play for free, leveling up characters and equipping more unlockable items and perks over time. That said, the app's quite pushy with its in-game purchases, constantly tempting players to spend money to buy new characters and outfits with which to differentiate their avatars from those of other players (though, as noted, the visual presentation is so poor, it seems unlikely many players would be interested in spending money on outfits). Put succinctly, Dead by Dawn Mobile is a not-particularly-impressive mobile take on a console and PC-based game that wasn't all that great to begin with. It might not cost any money, but you can't get a refund on the time you spend with it.
