Time to gear up again! Nintendo updated its eShop downloads for both Wii U and Nintendo 3DS for the week. If you're a fan of classic games in the Mega Man series, you're in for a treat.

Leading the charge are two Game Boy adventures featuring the Blue Bomber, Mega Man II and Mega Man III. In each, you'll take on Dr. Wily's minions using a variety of new weapons, acquired from his fiendish creations. Both of these black-and-white favorites are available now for Nintendo 3DS.

If it's a classic Wii U adventure that you prefer, Wario Land 4 will certainly amuse you. The greedy, treasure hoarding hero returns to tackle 20 all new puzzle-packed levels, using his charge attack to get out of harm's way quick. The game is the latest in Nintendo's Game Boy Advance re-release line-up for the system.

Fans of The Denpa Men will be happy to see the third chapter in the series, The Rise of Digitoll, now available in both full and demo form on the Nintendo 3DS. Once again, players will be able to catch and form parties of Denpa Men to take over dungeons, and eventually the world.

Also available in the 3DS shop is Kemco's 16-bit style JRPG Grinsia, where players set out to explore ancient ruins and face imminent danger while collecting treasure.

Last but not least, a handful of games are on sale on both systems. From now until next Wednesday, titles such as Jewel Match 3, Murder on the Titanic, Trine 2: Director's Cut and Aqua Moto Racing 3D are available at a discount, ranging from 25 to 50 percent.

Atlus has also slashed the prices of several of its hit games, including Etrian Odyssey IV: Legend of the Titan. If you're a fan of the series, definitely check these out.

Happy downloading!
