Hi,
You can find a short list about some F2P we / you could try and maybe like :
Realist:
-CrossFire : http://crossfire.gamerage.com (looks SWAT4 like)
-Alliance of Valiant Arms : http://ava.aeriagames.com (looks SWAT4 like)
-American Army : http://www.americasarmy.com
-Battlefield F2P : http://battlefield.play4free.com/en/fro ... andingPage (it's a small BF2)
-Warface : http://www.warface.com (looks CoD Like...but looks better than CoD) <Warning> CryEngine, by CryTek, so very very nice, but ask good computer specs.
SciFi:
