Oh hey, we got this game in the twilight years of the PS1 in a double pack with the PS1 version of the original Worms. Like Worms, it's also a turn-based strategy game where you try to eliminate the opposing teams except in 3D and in more realistic, non-destructible maps. Also, instead of cartoon worms you play as cartoon pigs.
Despite the ad hearkening back to Vietnam War imagery, it's actually spoofing WWII with endless HILARIOUS pig and pork-based jokes.
You can play as the British, Germans or Japanese, but maybe also the Soviets or the US, maybe both? Can't remember. What I do remember is that the Japanese pigs had horribly dated racist accents
