Your on to something here anon. Some weapons we see today were used secretly back in the day. People in special operations used weapons which were advanced for the time period. The game may not be set in the future but may be in the past where weapons were incorporated way before their time. In the 70's and 80's there was alot of agencies which put forward ideas of what things would be like in the future. Maybe the game incorporates this idea.
