'You're awake. Hold this bridge!' Your commander gives the order, and Chapter One, Bridgehead, begins on a winding road jammed with wrecked cars and debris. You pick crew cards, place them along the road and press START when you are ready for the first wave. There are 12 waves to hold, cash to spend on more crew and lives you lose when attackers get through. It is one of the free games like Bloons TD 6 on iPhone, played in the Roam app.
Setting up the defense
- Tap a crew card (prices run from $200 to $375) and place the unit beside the bridge road.
- Press START to send in the next wave; the speed button starts at 1x.
- Use the tent or barracks and the ability dial when a wave gets heavy.
- Keep your lives above zero through all 12 waves.
What makes the bridge hard
- A winding path, so placement on the curves matters
- Four crew cards with different prices to mix and match
- A short commander story that opens Chapter One
- A second chapter waiting behind a locked card
Next to games like Bloons TD 6
Bloons TD 6 and Roblox's Tower Defense Simulator work the same way: enemies follow a path, you place defenders beside it, and every wave hits harder. LAST LINE keeps that loop and swaps towers for crew units on a city bridge.
It starts small, with four cards and a clear 12-wave goal, which makes it easy to learn on a phone.
Tips for holding the bridge
Place your first units where the road bends. Attackers stay in range longer on a curve.
Do not spend everything before wave one. Keep some cash so you can patch a weak spot after you see where enemies slip through.
For planners, not twitch players
LAST LINE fits players who like to plan more than react. Most of the work happens before you press START: picking cards, choosing spots, deciding how much cash to keep back. Then you watch the plan hold or break.
The commander's lines and the chapter title give it a light story, so it feels like a campaign and not only a test map.
