Update []:
Spy Drops Gaiden officially has a release date!
As spotted by Gematsu, the Metal Gear-esque spy game from publisher Rainy Frog and developer Dadako is scheduled to launch on October 12th on Steam and will cost $4.99 / £3.99 / €4.99 (depending on where you live).
To celebrate the news, the people behind the game have dropped a new trailer, which also reveals the presence of retro bonus games (including one clearly inspired by on-rails shooters like Sega's Virtua Cop) and unlockable screen filters, just in case you want to swap the Pea-green colour scheme for something slightly more vibrant.
Original Story []: Metal Gear was one of the few classic '80s and '90s franchises to really nail the landing when it came to the transition between 2D and 3D, but there are many fans who look back on the 2D entries with real fondness.
If you're one of those people, then Spy Drops Gaiden (thanks, Next Indie) might be worth a look. It's a 2D spin-off of Spy Drops, a game from last year which was inspired by the 3D Metal Gear Solid series.
"Set on an island off the coast of Japan, infiltrate fortified bases, carrying out a series of classified missions to neutralize a global threat," reads the game's Steam page.
"Keeping to the shadows for cover, use stealth to sneak past guards, moving slowly to reduce noise, crawling under vehicles and avoiding surveillance cameras."
Showcasing "authentic GB style graphics, animation and sounds" and "classic stealth moves and take-downs", Spy Drops Gaiden has a playable demo on Steam now – so check it out and let us know what you think with a comment.
