You're part of a squad of marines in a conflict with somebody. You reach their capital only to learn of a highly unpredictable experimental device in their hands. Out of desperation, their forces set it off. The weapon begins to pull past, present and future together. The device gets stronger by the second, even beginning to bring back people (or what's left of them) back from the other times. You and your squad must battle through enemy soldiers, mindless remains of people from the past, strange and superior technology of those from the future, and even the device itself. You must shut off the device before it condenses time and space into a singularity, and ends the world.
I actually wanted to call it Singularity, I think it's much more deserving than glowing Spetsnaz fighting zombies controlled by eels.
