Remembering an old Gamemode

A few years ago, I played on a server where you had to fight multiple waves of enemies (antlions, zombies, etc) to defend a certain thing (I think it was called a nexus or something like that). There were multiple classes, each with their own weapons (and abilities?), and you could put downa finite amount of barricades before the game started as well.

You earned money after every game which could be spent on RPG-like items (eg a helmet which gave +3% to a stat). The shop / lobby was a tiny island with a house / pub during night time, and to join a game you could just hop on one of the boats.

What was the gamemode called, and are there still servers having it?

Only thing I can remember sounding like that is onslaught

Haven’t seen a server running that in a long time though

Thanks for the response! I’m not sure if it is the exact same thing, but it looks very similiar so I’ll check it out!

EDIT: Sadly, no server is running it, I’ll try it out in singleplayer.

EDIT 2: It is fun, but it isn’t what I was looking for. I played the gamemode before the Steam Workshop even existed, I think it was around 2011.

I have a small pseudo gamemode that sits on top of sandbox that’s triggerable by bored admins that’s similar, just without the economy.

Sorry, but this isn’t what I am looking for either.
