welcome to the brink forums, the main meal for any period of time is sarcasm, with a side of facetiousness. should you tire of this fare found on the brink forums then by special order you can acquire some of the finest sarcastic jackassery available on the interwebs.
on a serious note, your question currently cannot be answered accurately as full multiplayer has not been able to be played by anyone here (to my knowledge).
this being said if you like objective based gameplay, i.e. kdr and kills in general takes a back-seat to an overlying larger purpose then that leans more towards brink. if you enjoy taking more bullets to kill, requiring accuracy rather than “speed of spray”, then likely again it points more towards brink (haven’t played crysis 2 demo or such so not sure if this is the case, seems so from the vids however). if you like DM TDM and the like as game modes then brink is not the game for you as brink does not have these game modes.
at any rate brink is more akin to tf2 than battlefield. also do yourself a favor and don’t try to suggest that battlefield has any semblance of teamwork on these forums… this would be one way to acquire aforementioned “finest sarcastic jackassery”.
tldr; if you are looking for a game similar to cod or battlefield look ye elsewhere as brink is not similar to these, and those here like it that way.
