My game style?
Well, hmm, I think I will play single player to get the hang of the basics first and unlock the Heavy/Light to get a feel for those and get the customization options (especially the Eel!). Maybe do
some challenges (maybe I can find some people to co-op with?) to get some practice and unlock a couple of weapon goodies.
Then, I hope to go online and co-op with a someone or even with a random group from time to time on the weekends or whenever I'm free. ^_^ (Hopefully, I can find some peeps from this forum!)
Now, gameplay-wise. Hmm... It really depends on how the game works, really.
I'm one of those who like to stay with a party member or two at all times---like a Buddy System, lol: You got my back and I got your back---and keep healing/reviving dead peeps I come across.
Depending on the FPS game, I could be a hit-and-run backwards into cover kind of sissy gal or I could be a suicidal, panicky, but aggressive fighter gal, lol.
I really don't know until I get the game. There are many variables.
It really depends on how the fast the character moves, the map, my teammates, how the opponents play, the current mission, etc.
For example, in offline co-op Borderlands, I would go invisible and run forward and damage the strongest guy possible and bring the gunfire towards myself while my sister would pick them off from a distance with her rifles, while in Halo: Reach, we would try to separate and flank the bad guys from both the front and the back. In Call of Duty.... um.... well, I just run around and find cover and move around and try to flank enemies while sidestepping behind cover---oh, and grenade spam whenever I could, hee.
In Gears of War, I just stick behind cover, move around and shoot enemies in the back.
....Once I think about it, I'm a "flanker" (is that a real word, lol?) kind of gal, lol!
But basically, I'll be sticking with the group at all times or sticking near someone who's doing an important objective and try to defend (or cover?) him while healing/reviving nearby peeps from time to time.
