I beg to differ. I believe the Seeker is the most useless weapon in the game. Seriously, does it serve any purpose? So it homes in on others. It has such a large curve that it cannot home on others accurately. It's only useful for poor shots, IMHO, and you all shouldn't be poor shots (add to that it's the slowest gun in the game). =P

Pepper Spray rules. It is great for Tunnel Ratting and just plain cool. =P

Ice, well, is only good for Race or LANs, but that's still better than a gun that just hurts with a minimal tracking ability, is slow, and can't be upgraded with fastfire.

And TNT absolutely ruxors in Single. Also somewhat useful for keeping people of your tail in multi, even though it doesn't hurt (face it, if it did, it'd be too cheap!).
