SMG
Stinger
Spend 1000¤ for this SMG. A very fast but very imprecise aimless shot that will be perfect at short and medium distance. At a longer distance, the Stinger will not stay on the tile with a right-click in fast semi-auto and with reduced dispersion.
If the recoil is still very present, you can control the spray quite easily by simply lowering your sight a little. The Stinger is relatively versatile even if it obviously lacks damage compared to a rifle; it could be a very interesting choice in the second round or forced purchase. You may even prefer it to the more expensive Spectre variant.
Spectre
1600¤ and very slightly less damage than the Stinger. The Spectre has a decent hipshot. However, it has a very high dispersion and recoil and is difficult to control. Its only asset will be its rate of fire. Its right-click would even deserve an up so much it seems disappointing: it keeps the recoil and the dispersion of the shot at the hip and finally does not bring much. The Spectre will be a mid-range purchase not necessarily very convincing. For 600¤ less, you'll do just as well with the Stinger and for 500¤ more you enter the rifle category with the Bulldog.
