Alliance TowerDefense

Alliance Tower Defense is a Roblox tower defense where every match feeds the next one: you earn Coins while you defend, spend them on Summon to pull a stronger unit, equip the units you own into a team, then take that team into a harder mode. The Roblox page states the goal plainly — become number one on the leaderboard — and promises weekly updates on top.

It is young and loud. MrUpTime's Games published it on 25 June 2026; by 18 October 2026 it has passed 24.5 million visits, 19,264 favourites and a 92.4% like ratio, with servers capped at 35 players and the most recent patch landing 17 October. The in-game title is wearing its Halloween Part 2 costume right now.

Before your first match

• Run Easy first. The mode exists, the badge for clearing it exists, and roughly 45% of the players who ever earned the welcome badge went on to earn it — it is meant to be the on-ramp, not a warm-up you skip.

• Learn the lobby before you queue. The left menu holds Units, Trade, Shop, Settings and the AFK Area; the green Play button at the bottom drops you into matchmaking.

• Place units on the path, then upgrade the one that is actually working. Match cash comes from waves clearing, and the HUD shows each upgrade price as you hover it.

• Flip Auto Skip once the lane is safe. Easy runs 20 waves, Medium 30; the toggle turns a defended lane into quick Coins.

• Watch the countdown. The lobby runs timed events — the current banner counts down to a Piñata arrival — and those are the windows worth farming.

The difficulty ladder, with the official numbers

The ladder is not folklore: every difficulty has an official Roblox badge, plus a welcome badge for your first session, and the badge API publishes how many players hold each one.

• WelcomeFirst session
• Easy20 waves
• Medium30 waves
• Hard40 waves
• Insane50 waves
• CRAZY60 waves

Read that table as a filter: about one in two Easy clearers goes on to clear Medium, and the last three rungs stay close together — Hard, Insane and CRAZY separate teams far more than they separate casual players. Full breakdown on the modes and difficulty page.

Straight answers

Is it free to play? Yes. Matches cost nothing; Robux buys gamepasses and the four on-sale ones start at 99 R$ for double Coins.

Do codes exist? There are no verified active codes for Alliance Tower Defense right now. The game pays out through matches, the AFK Area and timed events instead — details on the codes page.

What is a summon? Coins go into the Summon system to produce a unit — the panel prices a single summon at 100 Coins and ten at 850 — and the gamepass list includes an x2 LUCK pass, which tells you the pull is a chance roll rather than a fixed purchase.

Which map should I queue? Each of the four maps is built around one difficulty: City with Easy, Canyon Bridge with Medium, Wild Desert with Hard and Camera Lab with Insane. Wave counts scale with them — 20, 30, 40 and 50.
