My friend and I, both in our late 40's, have been having a blast (literally) playing online coop in Insect Armageddon. It's just an all-out, action packed giant bug shooter, with tons of replay and entertainment value. The game can be played up to 3-player campaign coop, and up to 6-player survival horde mode.
If you have the game, or are thinking of getting it, $39.99 retail, and are an older gamer that simply wants to have fun when playing games, feel free to send me a message, and hopefully we can plan a time to all get together for some bug blasting mayhem. The following link is a video review of the game, and overall is fairly accurate. They rate it an 8.5, and I'm giving it a 9 for what it was designed to be. An old-school fun-filled shooter.
