Forget ye old days of knights and nobility when you had to stick a dragon with a sword to slay the beast and win yonder fair lady. These days, medieval mythological warfare can be done via the comfort of your own phone. Dragon Slayer fulfills your fantasy by allowing you to engage in magical combat with a host of dragons, and dragon-like creatures.
As with most fantasy-based games, you can collect and upgrade equipment to become more efficient at ending the lives of rare, gargantuan reptiles. Each dragon has its own set of skills, magical abilities, and weaknesses to challenge you. It doesn't hurt that the graphics on this game are actually pretty slick-looking, too.
Dragon Slayer is free to play on the Play Store right now. There are in-app purchases to acquire items, though. Hopefully, they'll stay out of your way if you don't want them.
