Rules: Duke Nukem gets his entire arsenal from his games, we’re assuming ammo is readily available to Duke, and everybody is in character

Round 1: Duke isn’t allowed any Mass Effect weapons, only his own.

Round 2: Duke can use Mass Effect weapons.

Bonus round: What members of the Normandy crew would get along with Duke and who wouldn’t?

Rules: we’re assuming the Martians/aliens in this scenario aren’t weak to viruses (so they won’t die a week into the invasion), the world of Trench Crusade is still at war during this whole scenario, the Martians arrive the way they do in each adaptation listed, and all sides are in character.

Round 2: Jeff Waynes Musical Martians (including the RTS Game)

Round 3: Great Martian War Martians

Rule: we’re assuming these characters survive the opening cutscene where Chief falls down, these characters will not immediately be infected by the flood in any flood mission by spores, the characters have access to their arsenal and abilities but they can use weapons from the environment, the UNSC and Sangheili will work with these characters (otherwise the Elites would’ve just glassed them when the flood is on earth) and finally all characters are in character.
