Beginner guide

Open the experience from the Roblox page linked on the home page. There is no browser build on the studio site. Pages that promise an "unblocked" copy are other people's copies, and I do not link them. If you do not have a Roblox account, that is the missing piece, not a secret web port.

Your first cash units are the cheap basic and uncommon troops. Read the cost column on the unit list and place something you can afford on wave one. Upgrade along the path bend where enemies walk the longest. Tags that say Slowing or Stun buy you time. Tags that say AOE matter once the path fills up. A single high DPS name from the tier sort is useless if you cannot afford the placement price.

New troops come from summons and from crates, then later from trades. Do not spend a mythic crate pull trying to "fix" a story map you are losing because the placement is wrong. Easy and Medium exist so the path teaches you. Nightmare, Endless, and Abysmal are later. An extra unit slot, when the client offers one, is an account upgrade. I am not quoting a Robux price for it because the shop UI changes and I will not freeze a price I did not read this week.

"Up the stairs" in old search logs is a lobby navigation hint, not a mode. The mode doors are on the modes page. When you are ready to swap duplicates, read how to trade before you accept a stranger's first offer.
