In Call of Duty Advanced Warfare you can upgrade your scorestreaks. After equipping the scorestreak you want to, for example a UAV, press Y on it to upgrade it. From there you can select up to 3 improvements, such as increased assist points, longer uptime or an inbuilt counter UAV. This will also increase the score requirement to be able to call in the scorestreak.
I have been playing Call of Duty for several years now and have put in over 1,000 hours into the multiplayer part of those games. When I started playing the Multiplayer of Call of Duty Advanced Warfare I really liked the movement system which refreshes the series. However, I don’t think they went far enough, I would have liked to be able to wall run, a feature of Titanfall I liked a lot, and perhaps stay in the air for longer. There are also a number of other issues I will go into detail later on.
The movement system in Call of Duty Advanced Warfare is quite extensive and advanced and gives you a lot of mobility. You can use it to get an advantage over enemies that aren’t utilizing the system.
The Exo Abilities in Call of Duty Advanced Warfare server somewhat similar to death streaks and certain equipment in past Call of Duties. There is one that is good on any class and others that are good in certain situations.
