Striker has the most amount of Pros to be honest.
- More Firepower, 12.0 vs Riot Gun's 10.0.
- Wide Shot for crowds.
- Weapon itself takes up less space in the attache case, 10 boxes vs Riot gun's 16 boxes.
- Stiker's 100 Round capability means you do not have to carry Shotgun ammo with you all the time, unlike the Riot Gun where you will need 6 boxes to have the same amount of rounds.
- Does not need to be pumped between shots, so you are not temporarily immobilized unlike the Riot Gun.
- Striker takes less money to fully upgrade. 392,000 pesetas vs Riot Gun's 415,000 pesetas cost.
- Striker fires somewhat faster than the Riot Gun for what it's worth. 1.10 seconds vs Riot Gun's 1.53 seconds.
All the Riot gun has going for it is the fact it does more damage to more distant enemies, but come on, there are better weapons for long range and mid range combat, TMP and Rifle for example, and grenades when in doubt.
EDIT: And on a different note, the Riot gun isn't even that much better than the standard Shotgun anyway....
