I wanted to make a tips for FPS novices, so if you have a tip to contribute, shout it out.
Tip 1: Ok, I cannot stress this enough. DO NOT be a Han Solo, charging after groups of enemies. You will obviously be blown to bits. I've seen this a lot of times on WFC and PSN.
Tip 2: Save medkits until your health is half-way. Don't waste your medkits if you've only taken one shot and have only a little health gone. You'll just be hurting your chances of being able to recover from sniper fire in the lower extremities and such.
Tip 3: Be stealthy. This technically also applies to Tip 1.
Tip 4: Do not use full auto while scoping. I've doon this a bunch of times and I've missed the enemy, they scoped me, and they struck me in the temple. It also alters your view of the enemy through the scope, so if you are shooting for a headshot, it can offcenter your aim.
