How do I get precise gernade fuse settings like 3.12 sec instead of 3 and mines on map fuse settings and replaying old game, where do I find those things? I forgot the other things I wanted to ask so I'll post those as I remember.

Those things are only visible in replays to aid the observer that hasn't participated.
They are no actual settings.

That's not possible (yet).

and mines on map fuse settings
Game options. When you set up a game (online or offline, where you select the teams, etc), click on the image with the question marks to the left. The settings for mines and oil drums can be changed there.

and replaying old game, where do I find those things?
You can find those in the User/Games folder in your Worms Armageddon directory.

Last thing

how do i set it so you can use infinate ropes in a turn w/ out hitting the ground, like the super rope setting on wwp. But not ammo, the ammount of times you can use the rope whilst in the air.

That's done by setting the power of the rope to 5 stars in the weapon settings.

And before you ask, no. That won't make the rope as long or as bouncy as the super rope mode in WWP does. Thankfully.

thanks, and is the infinate ropes or 5

and how do you make the landscape indistructable? last thing

In worms armageddon, I think you get indestructible landscape by completing mission 25.

Or you can use TeamED (go to www.blamethepixel.com and search for it under files - I'm to lazy to get a link) to edit your team and unlock it the cheat way. It will be in the options menu, click on the gold star (I think) and click the button that looks like the picture of the ground.

Or, you can use SchemeEddy (do a forum search this time).
