This plugin is more to the fun side.
When you die, even if you have a primary weapon, you will also drop your secondary weapon, and sometimes also your grenades. The grenades drop "from your belt" and explode/blind/spread gas, very funny effect really. The guy that killed you can get blown to pieces if he's too close and has low health.
I haven't really figured out exactly why this with the grenades happens, and it doesn't seem like you always drop a grenade when you die even if you had one. But this way makes it kind of fun anyway. The grenades gently drops from knee-height and go BOOM. Very funny.
At times it will also display "This weapon can't be dropped", not sure which weapon doesn't like to be dropped. Only weapons I stop the plugin from trying to drop is the knife and the C4...
Btw if you find out how this really works, please inform me. :-)
This should work fine with CS 1.6 as well as CS 1.5, but you should compile the plugin in your local machine because it looks at your NO_STEAM define in amxconst.inc and decides what version to compile.
