A lot or a little?
Parents need to know that G.I. Joe: War on Cobra is a free-to-play mobile strategy game available for download on iOS and Android devices. The game's based on Hasbro's long-running and popular G.I. Joe franchise, featuring characters that have appeared in toys, cartoons, comics, etc. Players build bases to gather resources and set up defenses, while simultaneously recruiting and training units to attack other bases. Combat is constant, though it consists mainly of flashy effects and explosions, with no blood shown onscreen. There's a heavy push for players to purchase in-game items and currency in the shop, though these purchases aren't necessary to play the game.
