Okay, so it's not the full 3DS experience, but a more "watered down" version. Here are some details and screenshots:
The title screen looks pretty good, I have to admit. The game is focused on the multiplayer aspect, allowing players to communicate over locally via Bluetooth or globally via WiFi. Players can host or join a game with four characters, either other players or AI. The game can be set to be a free-for-all, or two-on-two mode.
You can choose from the three main characters. Chris is slow, but packs a strong shotgun; Jill moves quicker, and her SMG takes out health pretty quickly; Wesker is a deity. Period.
The aim is to avoid or defeat any Ganados on the map (choose from fort and docks from RE5, as well as monastery from RE4), and eliminate your opponent players. In addition to weapons and healing items, you can also find Action Items, which temporarily alter the game rules (such as banning healing items or increasing enemy defense).
If your character is injured and enters the "red zone", you will move a lot slower, cannot change weapons, and also your health will continually decrease until either you are killed or healed by an ally in Team Battle Mode. The healing animation is... rather unfortunate. There are also bear traps and proximity bombs on some maps, and unlike RE4, you cannot disarm them with your weapons. The only way to get rid of them is to set them off with your own body.
You can play the game in single player mode too, with three other AI as opponents. Apparently, the online version is either too laggy or doesn't play at all, with many players citing the "connection timed out" error that is so infamous on the iPhone platform.
I find the game quite a good blast, especially with friends (over local connection), however, it may become repetitive. Especially when you attack an opponent, you literally just stand there and shoot them while they do the same to you. Also, Ganados always seem to attack only you, but never any opponent AI characters (or allied AI). On top of that, the controls are quike klunky; auto-aim is on by default, and is prone to spoiling headshots. Considering what Capcom could do for RE4 Mobile, I expected better from them.
Anywhoo, I expect the 3DS version will be much, much better than this. If you're willing to risk it, the App is currently on sale for $4.99.
PS.
Remember when I posted a review of Resident Evil 4: Mobile Edition? We all complained about how it covers only half the original storyline, and ends abruptly at Verdugo, whilst wondering if Capcom would ever complete it. Well, guess what? They answered our prayers. The App has been updated, and now the story is extended to the Saddler battle, complete with writhing eyeballs on his legs! I couldn't get a video of the final battle just yet, but here's a recording I made of Chapter 1 of Mobile RE4: http://www.youtube.com/watch?v=grFQqgRNiZI
