Scheduled maintenance yesterday suggested Nintendo would be updating its Switch Online Expansion Pack service with some additional Sega Genesis/Mega Drive titles and sure enough, three more games have now been added to the service.

The latest additions include Light Crusader, Super Fantasy Zone and Alien Soldier. Here's a bit about each one, courtesy of Nintendo:

In Alien Soldier, the acclaimed developers at Treasure invite you to take on the role of a bird-man with steel wings in his fight against 25 bosses. In this challenging game, you can learn new tactics with every defeat … or take advantage of that handy Rewind feature to perfect your run!

Super Fantasy Zone has you powering up the ever-appealing Opa-Opa across eight colorful planets!

In Light Crusader, also from Treasure, let nobility light your way through a lovingly crafted action-RPG.

To play these games on your Switch, you'll obviously need to have a Nintendo Switch Online membership and a subscription to the higher-priced Expansion Pack tier.

This update follows on from an Expansion Pack update last week, which added the Nintendo 64 classic F-Zero X. What do you think of these titles? Have you tried out the Expansion Pack yet? Leave a comment below.
