Yes, everybody else already mentioned that you can leveling up by playing Wolfpack only, but for the first time it might seems a bit confusing. Yes, i know, by playing Wolfpack Discovery you will be familiar with the basics pretty fast, but still i would like to give a more detailed tutorial with this solution and explain how to play it, which gameplay elements are important to get the most points in the different waves and situations. You can either play it with friends or solo, it doesn't really matter, but i prefer to play alone because it's much quicker and in this case you don't have to rely on anyone else. Let's get start with the HUD elements:
- Target Indicator: This circular thing can be found on the bottom of the screen and it shows you where is your target and how far away he is from your position. The more it fills, the closer you get to your target. When the controller starts rumbling, you should stop running, because if you are acting suspiciously near the enemy, your Detection Meter will decrease.
- Detection Meter: It can be found on the right on the screen, right above the avatar of your target. It has 3 different parts, each provides more points as your meter fills the bar. The slower you walk, the faster it gonna fill up. First part provides 150 points, the second provides 250, the third 350 and when it reaches the maximum, it gives a total of 450 points for the kill. Let's mix it with the Focus bonus.
- Focus: When you are near your target, an (X) icon will show up above his head. If you wait around 5 seconds, a circular element will show up. As it fills up it provides you 50 points, but if you wait it to fill up fully, it will grant you an extra 150 points. (Along with the Detection Meter points)
First thing first: you really want to play all of the maps, because completing a Wolfpack game on every maps grants you a bonus. Also, if you're able to play one or two games every day you'll recieve a daily bonus too, which can further boost your level.
The actual gameplay is not different than the one you could see in AC3. In every round you'll get a different objective. Mostly it's just about to kill a moving or standing target. I suggest you to always try walk next or behind him, and wait until the detection meter reach the maximum. (450 points) if you are able to blend in a crowd during your hunt, you'll get a 2.5x multipler up to your current points. After a few rounds you'll have a chest defense mode. If you're playing on Fort St.Mathieu you'll have an easy job. There are quite a few vantage points and benches near the area. It's a good chance to boost your points with acrobatic, aerial or hidden kills. In infection mode you have to pick up either one of the three medical packages to be able to eliminate the infected targets. It's all about speed. Pick up a package and kill your targets as soon as possible. If you got hit, you have to pick up another package. If you have two or more targets, using the coin throw ability can easily distract the decoys, so you will know for sure who your actual target is. Standing too close next to them can cause you being compromised, so keep your distance and don't make any sudden moves.
It might take a few games to get used to it, but trust me, it's not that hard as it looks like. Also, consider completing the bonus objectives too, because they also provide additional points. Two of them are active at the time, but since they are always cycling through, you will know how and which point of the map you should complete them.
Either you play solo or coop with 2-4 players, the key is always patience. Running and fooling around is just a waste of your precious time, and while you can easily reach level 15 or 19 by that way, in the end it won't be enough. Even if you are able to hunt down the extra target which gives you an additional 45 seconds. If you play with patience, you'll end up in more than enough time anyway. (I usually had 6 minutes, but one time I managed to have 8 minutes as well)
It's not a proper solution, but rather a detailed guide for Wolfpack. If you not willing to join boosting sessions all the time, this is the best way to reach level 55 easily on your own.
