Skill issue? More like a "not having two Virtua guns" issue. Some sick freaks really thought it was fine to design a game around the requirement of having two of the same peripherals.

Could not get past the first level. Your rate of fire is so slow that it's worthless against the amount of enemies that occupy the screen at any given point in time, and damage received is so poorly communicated that it almost feels passive so long as a target remains visible. Upgrades provide you larger clips and rapid fire, but waves are so intense that you're still likely to die between recharges, and if you die you lose whatever you're carrying, which pretty much puts you in such a bad position you might as well hit the reset switch on the Saturn.

I own one Virtua Gun and you bet your ass I'm not going to buy another just so I can play SCUD: The Disposable Assassin.
