DotEmu is a publisher that specializes in re-releasing older PC games for modern play. They have a decent sized offering on Google Play that include the Metal Slug series, and Another World. They have put two of their offerings on sale in conjunction with Google’s Summer Sale for Play. The games that they’re discounting are R-Type II and the Double Dragon Trilogy.
Having played the latter, I can recommend it for that price. It’s a decent port if you’re looking to enjoy a blast from the past that’s an ’80s beat-em-up, especially considering that you’re getting all three. In Double Dragon, players are attempting to rescue, and later avenge the death of, an abducted lover. In the third installment, players are seeking the eponymous Rosetta Stones.
The R-Type series is one of horizontal shooters, where players control a fighter ship and strive to take down the Bydo Empire. For R-Type II, Dot Emu added a pair of new weapons: Search Laser and Shotgun Laser, and a new anti-ground unit bomb. Both are on sale for $0.99 for a limited time.
