This is an incredible list of shooters. A great mix of PC and next-gen console shooters. Some I actually never heard of.
Jun 21, 2009 at 23:06:23
Errm… Gears of War isn’t an FPS, it’s a TPS. I think Halo 3 should be moved down the list as you not only have to pay for it, but you also have to pay for XBL in order to play it!

@Lolmeister
Thank you for your comment. Good points both and will be considered for revisions. Thank you.
Jul 16, 2009 at 21:58:39
Great List, I agree with Lolmeister though. Also what about Combat Arms? Its vert good and is #1 in a lot of lists. It is an MMOFPS that is about 1 year old and is very Popular.
Also Thanks for the great List!
Jul 20, 2009 at 11:24:12
combat arms aint that good its full of glitches, hackers and super laggers… and nexon is making game more and more real cash based it will probably be soon sold or made into monthly cost… people in that game also have serious problems with connection which make them lag a lot and game doesnt seem to understand “lag” person wont take at all hits while he lags no matter how much you shoot him.
im intrested why aint CS 1.6 in this list it is still one of the most popular games imo cs 1.6 has succeeded in everything… no glitches, no cheats (vac works realy well actualy).
Jul 21, 2009 at 22:12:13
I for one am glad Combat Arms isnt on the list. The community is horrible. Every time you get a kill you get called a hacker lol.
Glad to see Cross Fire and Quake Live in there. Great games, those two are. Sweet list.
Jul 27, 2009 at 19:09:37
Halo 3 is better than all those games. Its fo sho the best mmofps ever.
Aug 16, 2009 at 12:33:08
asd
what is cs 1.6 i never heard of plz tell me.
Aug 23, 2009 at 10:11:58
what about Soldier Front? it is a very fun FPS. I think its by the same people that made Huxley
Aug 23, 2009 at 23:39:04
Why isn’t CS 1.6 o n the list? I played most of the online junk shooters out there (Halo, Quake suck)… I’m playing battlefield 2 right now… But in Eastern Europe… by far the most played game in the last 5 years has been and still is CS 1.6 out of all shooters… and DOTA out of strategy games.
CS 1.6 is the best shooter available even if it’s very very old.. most people still play it.

personaly i dont concider combat arms or quake or any of them games mmofps, they are not mmo, you have server with up to a certain amount of players, like any online fps, a mmofps would be games like ww2 online or planet side. i also agree combat arms has alot of issues with nexxon and its player base, but it still should have made the list. i dont think the games not curretnly out should be on that list, games in deveopment (not counting beta) cant be called or rated in the best level, because without a wide varity of players theres nothing to base it off of. games that were contrey specific should have been dropped as well. one game i would have loved on the list was left4dead, not a fan of zombie games but the co-op on that game was just unbelievable.
Sep 12, 2009 at 07:37:53
come on …………………..
where is combat arms in this top ten people
Sep 29, 2009 at 09:31:45
Point Blank Online is very popular in my country, and i personally think that it’s better than CS Online.
Oct 16, 2009 at 03:59:38
far wat happened to combat arms D:
Oct 16, 2009 at 21:06:56
OP7 is one of the best on there, I havnt tried Huxley, but it looks ill. The problem is that I moved to Thailand for work and its hard balls to find games that have servers up in south asia. When I got here I tried OP7…no luck I was still on an US server. I am lost, guess I will have to rty my hand in CS 1.6.
Anyhow the list looked rad, except for gears of war…that is a dodgy game.

1. Team Fortress 2
2. Call of Duty 4: Modern Warfare
3. Left 4 Dead
4. Battlefield 2
5. Counter-Strike: Source
6. Call of Duty: World at War
7. Battlefield 2142
8. Crysis Warhead
9. Enemy Territory: Quake Wars
10. Half-Life: Counter-Strike 1.6
I got this list at “internetgames about com”. Sometimes sites opinions are a bit of this mixed
mixed with a bit of that instead of accurate information.
Key is to get accurate viewcount of various multiplayer games hosting servers and the amount
of players playing.
A little bit more to it than opening All Seeing Eye one day and comparing it might be just
a generality of what was a hot game for a while then some moved onto other games.
Like if you go to IGN, Gamespot, Gamespy or even some Youtube reviews top lists vary and
with some sites that means by a huge margin.

@BIAS
Thank you for your comment and your top 10 list. Unfortunately by looking just at numbers of players you may be focusing too much on games that just had a large advertising budget. Many of these are also on their way out.
