The last Humble Bundle for Android just ended, but if that wasn't quite enough to slake your desire for gaming on the go, may I interest you in the Humble Mobile Bundle? The primary difference between this one and the last is that this package won't include Steam codes for the desktop counterparts. Only Android. However, the four primary games you get are Contre Jour, Anomaly Korea, Plants vs. Zombies and Bladeslinger. If you pay more than the average ($5.38 at time of writing, but ~$7 is typical throughout the life of the sale), you can unlock Metal Slug 3 and The Room.
You know us, here at Android Police. We have simple tastes. We like old school games, we like getting things on the cheap, and we like things that go boom. Which means that this sale on Metal Slug 3 is right up our alley. While this title is normally around $7, it's available for $2 right now on the Play Store.
This game originally came out for the Neo Geo and its nostalgic graphics have been lovingly recreated for Android. You can also link two handsets together via Bluetooth to play cooperatively with friends. Not bad. Get in on the explode-y action via the widget below.
