Any idea how could I create 2 player option in singleplayer game?

If you want local multiplayer, first you'll have to create a second "mob" variable on the client type. Then you can set up all of your keyboard macros to include a parameter specifying which player the macro is for. You'll want the macros to call verbs defined on your client, which can then pass them on to the proper player mob.

That's the basic idea. You might also want to set up a custom camera to center the view on the two mobs, or limit player-two's movement to within the view.

If your players have Xpadder or Joy2Key, it should work quite well.
oh nice ... thank you. :)
