Co-op Tower Defense with Friends
Most tower defense games are single-player – co-op is often just a side mode with separate maps. Here you defend the same map together, share every coin and plan your defense as a team. And it stays frustration-free: anyone who steps away or leaves holds no one up.
Play together in three steps
- Open the game – the start screen is there instantly, there's no sign-up.
- Click “Copy invite” and send the link to your friends.
- Pick a map together and hit “Start game” – anyone can start the match.
Teamwork, not side by side
- One shared map: everyone builds the same defense network, and your teammates' cursors are visible.
- Drop-in/drop-out: latecomers join the running match – no matter which wave. Anyone who has to go just leaves; the match keeps running for everyone else.
- Everyone has their own wallet; income is split evenly. Only the builder may sell a tower – anyone may upgrade it.
- Support works for everyone: ammo depots, spotters and marks boost your teammates' towers too.
- Combos across players: one lays oil and wire, the other places flamethrowers and AT guns behind it.
- The Atlas belongs to everyone: upgrades like the Minigun, Armored Gate or Protocol Zero are funded together.
- Start a match and share the invite link – the room code alone is not enough to join (streamer protection).
- Players inactive for a while count as away: their gold goes to the active teammates until they return.
- Any player can pause the match for everyone.
Frequently asked questions
Can you play tower defense online with friends?
Yes. Start a match, copy the invite link and send it to your friends – they land right on the same map. Up to 4 players defend the Atlas together.
Can you join or leave a match that's already running?
Yes. With the invite link, friends can join at any time – even at wave one hundred – and play right away as long as a slot is free (up to 4 players). Anyone who leaves keeps their towers standing; their gold goes to the teammates, and reloading brings them back.
What happens when a teammate goes AFK?
Nothing bad – nobody gets kicked and the team stays in action. Anyone idle for a while counts as away: their gold is automatically shared among the active teammates, and new income only goes to them. As soon as they do something again, they're back in the game.
What does the game cost – do I need to install anything?
Nothing. Tower Together runs for free in your browser – no download, no account, no sign-up.
How is gold shared in co-op?
Everyone has their own wallet, but all income is split evenly among the active players. Nobody can grab the team's gold; you fund Atlas upgrades together in partial payments.
Can I play alone too?
Yes. Waves are the same solo and in a team – as a team you just share gold and tasks. Teammates can join at any time.
Can viewers just join while I'm streaming?
No. The room code in the address bar is not enough – only people with the private invite link can join. The link is never shown, only copied to your clipboard.
