Pffft ... played to many to remember.
some of them are solo FPS, and lately some more multiplayer/online shooters.
With mixed results, it all depends on the shooter...
I'm a bit of a gung ho aka aggressive player, so my K/D ratio is a tad lower in games like BF4 (but i'm pretty good and know as a Tank killer... with C4... i love doing that :))
But i'm slowly improving, and if i make at least a 1.1 ratio, i call it a good day. (been a while tho, that i played it ... so i'm a bit rusty)
I perform a lot better in games like HAWKEN it seems, but then again... i played it with a TEST member and working together is always better.
Still have some Shooters (1st and 3th person) installed that i play or still need to play, like :
Battle Field 4
Arma 3
PlanetSide 2
HAWKEN
Titanfall
Blacklight Retribution
Crysis (whole serie)
Bioshock (whole serie)
Brink
TF2
Borderlands 2
And just finished Wolfenstein, The new Order
(and some more stealt like shooters... i love those, like Sniper, splintercell, Thief, Dishonored and Deus Ex ... etc etc)
You can always look up my steam profile, or add me to the list... same name as on this forum (Choppanob)
But i see myself as mediocre at best... or the game is supporting a Kamikaze style of play like i do (try and flanking and such) or blow up vehicles with C4 (next stop... C4 a chopper or plane in mid air... as a foot soldier)
