I suppose most of the nD players knows what the CS mod "deathrun" is since neonDragon had their own deathrun server, I will explain it anyway. In the mod Deathrun the Counter-Terrorist's (CT) are supposed to finish the map while the Terrorist's (T) are releasing the traps they got, when the Counter-Terrorist(s) have finished the map they got the chance to get a gun, or they can leave it. Then their job is to kill the T(s) that tried to kill them earlier. When the T or all the CTs are dead, the round is over.
Scoutknivez is kinda like the regular counter-strike(CS) mod which is aim, but here you're ONLY weapons are the scout and knife. The point of this mod is like all the others, to kill the enemies and win the round.
Pokemod might be new for this community, it's a mix between Superhero, aim and a little bit Wc3 in this mod you get to choose ONE pokemon the first time you join, then you can level it up by killing/enemies/defusing the bomb/planting the bomb, just like the pokemon games and show your pokemon can evolve and get stronger, you can have with you a maximum of 7 pokemons. How to get other pokemons you're wondering? You can buy one the beginning pokemons (Pikachu,Squirtle, Bulbasaur, Charmander, Meowth) for 16000$ or you can find pokemons in the enemies spawn or catch them, you can buy different balls, stones, items etc at Pr.Oak
Hide N Seek
In this mod the T's are supposed to hide from the CTs, the Ts only got 2 flash, 1 smoke (Freeze) and a HE nade. While the CTs only got their knife, this mod is really popular in CS since you can play it on every map(with blocks) and no-block which can be played at spesific maps made for HnS. If the CTs kills all the Ts they switch side, CT>T, T>CT. If the Ts win the round they stay T, so there won't be any switch.
Keep in mind that this is just a few examples of which mods you can have!
As you can see votemod is like SEVERAL other mods in ONE server. It would be alot of variation, and I think it would attract alot of players since it's really rare to find a server like this.
