Closing thoughts

The MP5-SD is a silenced SMG that occupies the same loadout slot as the MP7; it's unique selling point is its silencer as the former deals more damage. Unfortunately this often is not enough to justify its high purchase price. However, a cheap (compared to a rifle) weapon that is silenced and has a high rate of fire can have utility in certain scenarios.

As the most expensive SMG at $2350, purchasing the P90 is hard to justify. What it lacks in practicality it makes up for in aggression, with high armour penetration, extremely fast rate of fire and massive magazine all contributing to a style of engagement that can overwhelm unprepared opponents.
