Many of you probably know of the youtube channel called levelcapgaming. This post is for the people who dont.
Levelcap is a bf3 player and youtuber that posts videos of the battlefield series of games. His videos center around the focus of being the best battlefield player you can be. He has many tutorials for things like cornering and peeking. And just generally being a great battlefield player. Levelcap himself is a really really good battlefield player. He played competitively for a long time but has dropped off that scene lately. His main video types include Loadout, sniper sunday, double vision, game plan, and squad up. Loadout is a series where he takes loadouts that are posted in the comments of his videos and try's them out, then gives his opinion on them. This series is great if you want to find enjoyable, effective, or just plain trolly loadouts. Sniper sunday is a series where he (and sometimes other youtubers/battlefielders) plays battlefield using only sniper rifles. Game plan is a series where levelcap does a live commentary and says what he is thinking while playing battlefield. These videos are useful because they allow to have huge insight on how an amazing battlefield player plays. Squad up is a series where he plays battlefield with 3 other youtubers/battlefielders in a squad. This series is ussually played in team based game modes such as conquest or rush. His last series is called double vision. This series is where levelcap and another youtuber get in a vehicle in battlefield (ussually choppers) and own it up. The reason this series is called double vision is because the point of view switches between both people who are playing.
