As a gamer, I hate this movie already.
Let's look at Doom.
Scientists on Mars open a gate to Hell through teleportation technology. Marines are sent in, all but one dies, the last one (you) stops the invasion of Earth.
In the movie.
Scientists on Earth create a virus that turns people in to zombies, and SWAT teams are mobilized...
*pukes*
Doom 3 is better than this movie will be.
