Singularity is a 2010 first-person shooter video game. The game takes place during the present and the past switching between both timeline for the hero objectives. In the past we gotta kill the Nazi Soldiers and find the objective given to alter the present
Along with that your still stuck in a present where there are mutated freaks running about everywhere in the island ready to take down any human they win and devour it to their fill. I'll recommend the to those whole like US-Russian war based games plus added horror and survivability.
It's a good game and the graphics compared to nowadays mid price games.
