Distant Past

"Distant Past" thrusts you into a retro first-person shooter experience reminiscent of classics like Doom and Quake. 

The year is 2676.  The population of earth has skyrocketed to 14 billion.  Thankfully a resource has been discovered that could help.  Eternagerm is a mineral that increases crop return 10 fold.  However, the resource is so scarce that the planet is on the verge of World War 4.  

G.U.A.R.D or the Global Unified Armed Response Division is determined to prevent this war.  Even if it means going back in time and stealing the resource from other timelines.  

The reward would be worth the risk.  Right?
