But how do you know it would feel like that, if you haven't experienced it yet? Also, read the suggestion about modifications. That portion intends to have the weapons modifiable in a variety of ways to accommodate the time period we currently inhabit, in the game. Say, an M416. You can choose to upgrade it for a certain damage type, such as Shock, or Void (At the cost of damage). Otherwise, the damage can be increased (At the cost of damage type). Also, the damage shouldn't be outstanding. Only to a point in which the weapons themselves are very flexible in customization to be on par with "up-to-date" weapons. In reality, the current weapons now are still practically "modern" weapons with different paint, tracer colors, and effects.
