A long time ago I played a game similar to boom race but you could move and you only had grenade so you would lay nade and jump just before it explodes and launch yourself over obstacles. It was a lot of fun but now I can't find any maps or schemes for this game, can you help me with them? Preferably wmdb maps and wsdb scheme.

Lex has made a few nade jump boom race maps.
I've attached a few replays, you can extract the scheme/map.

You'll need rubberworm to view/play.

Thanks but this is kinda similar to normal boom race cuz you have no retreat time plus with weapons like hhg you don't really need to jump before explosion.

Well both those maps, and I'm sure many others are doable with nade jumps only. Why not just make the scheme you want and crack on?

Of course you can do that it's just I remember that there were some maps that are designed around nade jumping.

yah there was a chally hosted here at TUS, check dis: https://www.tus-wa.com/challenges/challenge-259/
