Earth Defence Force - Insect Armageddon

Whereas the previous game was missing an online component, but provided classic split-screen co-op antics, Insect Armageddon has ramped things up to "modern" gaming as it were. Two-player split-screen co-op returns as well as a full three-player online co-op campaign, and a larger 6-person online survival mode.

Beyond this, there are somewhat "modern gaming" standard special features including an art gallery, though, unlike a lot of games, players don't need to unlock this one. EDF: Insect Armageddon's art gallery is available right from the start.
