Your target is to score 15 kills using a P90. The weapon is characteristic for its huge recoil when going for longer bursts - first four bullets stick, but the next two ones start to move up. If you've kept firing, the weapon will start to spray, forcing you to control the weapon by moving the crosshairs to the bottom right. The map itself is a small area with a bombsite. There are 3 interesting spots that can be used as an ambush location. You can find them below.
The left turn leads to stairs that can be used by our opponents to enter the building. It is also the end of the play area. You can try to lean out a little and check if there aren't any enemies approaching the location. If you've noticed or heard any movement, hide behind the corner and eliminate the attackers. You can also throw a flashbang to slow down their progress.
Proceed forward from the spawn area to find a small wall that is also a vantage point for the pathway often used by your enemies. Before you assume the position, check the pathway for incoming enemy. If you've found any opponents, either return to your vantage point and take care of them, or simply alert your ally and retreat to a more safe area. If you've noticed that the enemy decided to use the stairs, double back to the wall and get ready for an attack.
Make sure to check the small hut next to the spawn area, as there is a ladder inside that can be used by your opponents to get access to the bombsite without being noticed. Include the hut in your rounds, especially that the top of the ladder is a great vantage point that will enable you to quickly dispose of the incoming opponents.
