Definitely toned down from Titanfall, but if you liked that game you’ll probably like Apex too!

I would say stress about the character selection too much, you’ll find characters that you enjoy more over time but abilities don’t overshadow good gunplay in the game.

A few small tips:

• heal your shields before your health (most of the time). Shield items are slightly faster to use than their HP equivalents but provide the same amount of healing (e.g. shield cell = 25shields ~2 seconds to use, health pack = 25hp ~3 seconds to use)
• when you kill an enemy and they drop their death box, you can loot their shield from the box to instantly recharge some or all of your shields. It can be really helpful even in the middle of a fight or if you know another squad is coming to third-party you
• don’t get too caught up looting, you’ll get good stuff a lot more quickly by taking out other teams who have already looted for you
• always be aware of where your squad mates are and make sure you’re close enough that you can get over and help them if need be

Best way to learn ofc is to just jump in and play some matches. Have fun!
