UPIXO in Action: Mission in Snowdriftland

Mission in Snowdriftland (or as in the Flash version UPIXO in Action: Mission in Snowdriftland) is a pixel art platformer published for Steam (with a history of being an online Flash game in 2006 and sponsored by Nintendo of Europe) created by German studio tons of bits. The game was used as an advent calendar advertising various Nintendo products from December 1 to December 24, 2006, with an additional level added each day. It was supposed to be taken offline on January 14, 2007, but was delayed until January 16. The game was brought back on December 1, 2010, this time to promote upcoming WiiWare titles for the Wii, but once again removed in 2011.

A remaster of the game with new features, more content and technical updates was later released on Steam on December 1, 2021.

Storyline
El Pix, an evil penguin, has stolen video game artifacts from the secret archive of Video Game World, and made off with them to his lair in Snowdriftland. UPIXO (United Pixelheroes Organisation) has no clue what to do, seeing as the region is far too cold for anybody to survive. However, UPIXO boss Chief Tapir's assistant, Professor Schwabbel, spots Chubby Snow, a snowman video game character, who is complaining at the front desk because all his video game roles have been bad so far. It now depends on Chubby to get back the stolen artifacts.

In the original Flash version the only difference was that El Pix has stolen game files from the Human World.

Gameplay
While Mission in Snowdriftland plays like a traditional pixel art platformer game it can be also played as a digital advent calendar. Due to its history and concept the player can open a door each day of December (starting on Dec 1) and play one level per day until the final endboss stage (unlocked by opening/beating door/level 24).

The game is divided into 4 worlds: Lake, Forest, Mountain, Cave. Each world has 6 stages, for a total of 24. Each stage contains 24 snowflakes. Once the player collects all 576 snowflakes (24 in 24 levels) a huge Bonus Level gets unlocked.

At the end of each world a miniboss stage is accessible. Beating the miniboss will clear the way for the next world. The miniboss of world 4 (cave) however will unlock the endboss stage, where Chubby will take on villain El Pix in a final battle.

Health bar: At first, Chubby can only take 3 hits before he dies. A few levels contain hidden power-ups such as extra heart containers, which will add a permanent extra heart to Chubby's life meter.

Differences in the original Flash version: Collecting 24 snowflakes in a level unlocked downloadable rewards for the game/console files of that level. There was no bonus level and no minibosses.

Restoration
Technical upgrades for the Steam/PC version:
 * HD remastered graphics (characters, objects, backgrounds)
 * Parallax scrolling
 * Controller support
 * Save game slots

While the flash game was no longer available due to limited accessibility, the game was still playable on the developers website after January 16. The site was meant to be password protected, however this was non-functional due to a programming bug.

The flash game was re-released in the winter period of 2010 to promote indie games available on Nintendo's WiiWare online market, though it was subject to the same timed release window, making the game only accessible for a few more days.

Web browsers would also cease the use of Adobe Flash Player in December 2020, the framework Snowdriftland ran on. However, BlueMaxima's Flashpoint saved these experiences as well as reviving Snowdriftland, which is now playable in their catalogue.

A video made by YouTuber Nick Robinson, titled "Mission in Snowdriftland: Nintendo's forgotten Flash game", revealed that a remaster has been announced for a Steam release in late 2021 with the developers also possibly creating a Nintendo Switch port of the game in the future.
