Resident Evil Revelations was the first major release on 3DS this year, and it's pushed a lot of buttons with an impressive campaign and online co-op mode. Like all video game projects, however, the final product doesn't include everything that the developers initially intended, as producer Masachika Kawata and director Koshi Nakanishi recently told IGN.

The major exclusion from the final project was an online co-op campaign mode, which was eventually replaced by the more fast-paced 'Raid' mode.

We had online co-op for the story campaign up and running in the early stages of development, but feedback from testing indicated that single-player Resident Evil was scarier, so we left it out and focused our attention on improving the single-player survival horror experience. Since we'd done the groundwork and it would have been a shame not to utilise the 3DS's wireless features, we added Raid Mode.

Also discussed were early plans to have the game start with the ship arriving in a port, but ultimately the sense of exclusion and isolation of being out at sea was preferred: remnants of this original plan can be found in the land-based Terragrigia and mountain sections. For those who also wanted to see a greater variety of enemies, that was also something strongly considered.

We were inspired by the incredible variety of real-world marine life, and some of the unused enemy designs were based on octopuses, sharks, sea anemones, tube worms and the extinct abnormal shrimp. We even got as far as designing their attacks but, in the end, we couldn't include most of them for one reason or another.

Most of the creatures were created first and foremost as functions of the game's difficulty curve and level design, but some started out as artists' rough sketches of ideas that became either brand-new enemies or old enemies with new twists.

Throw in the abandoned idea for the cruise ship to capsize and some fairly dramatic features were left out. That said, the final product is still one of the best experiences available on 3DS so far, or so we thought in our Resident Evil Revelations review.

Do you wish any of these ideas had made it into the game, or are you happy with the final result?
