Nintendo has just added four more games to the Sega Genesis / Mega Drive app for the Switch Online Expansion Pack service.

The latest editions include platformer Toejam & Earl in Panic on Funkotron (1993/94, Johnson Voorsanger Productions), action platformer Vectorman (1995, BlueSky Software), and the run & gun Wolf of the Battlefield: Mercs (1991, Sega). Japan has also received the same three titles this week.

Nintendo has also noted how the original packaging of these games is featured in the trailer and the "play to win" $25,000 contest for Vectorman has "ended" - so no, you can't win money if you complete the game.

Here are the official descriptions and screenshots for each game courtesy of Nintendo's Japanese website:

Toejam & Earl in Panic on Funkotron

"The second installment of the cult-popular exploration action game. Toejam and Earl were able to safely return to their home planet, "Funkotron," but now they find themselves invaded by humans! Use the magic bottle to capture the humans who run around the peaceful planet as if they own the place, and send them back. You will clear the game if you find all the humans and forcibly return them at the goal. This is an exploration-based side-view action adventure with fun characters that are now more expressive."
