City Defense is a free online shooting game you can play right here in your browser, with no download and no sign-up. City Defense puts a target in front of you and a weapon in your hands. Aim, timing and knowing when not to fire are the whole game. Its tags tell you what to expect: you place defences to stop waves along a path; fast reactions and constant movement are the point.
About City Defense
This is a real-time strategy tower defense game. You need to deploy your troops and obstacles to defend against enemies, and also upgrade them strategically to eliminate each wave of enemies!
The genre lives on enemies with distinct behaviours, satisfying hit feedback and waves or levels that build up. City Defense understands that, and it shows in the first minute of play. Under the surface it is a test of situational awareness and aim, dressed up in tactical presentation.
How to play City Defense
- Start by clicking the big play button. City Defense loads inside the frame; give it a moment, especially on a slow connection.
- Follow the on-screen prompts. The developer describes the controls like this: Mouse click or tap to play
- Take a few practice shots at the first targets to learn the aim speed, then move on to prioritising the dangerous enemies.
- Use the full-screen button under the frame for the best view, and keep an eye on the score, timer or health display so you know what the game is asking of you.
Controls
The controls in City Defense are straightforward once you have seen them written down:
| Input | What it does |
|---|---|
| Mouse | Mouse click or tap to play. |
| Tap (touch) | Mouse click or tap to play. |
The controls are tap and drag based, which makes it comfortable on touch screens as well as with a mouse.
Tips and tricks
- Move between shots. Many shooters make you an easy target only when you stand in one place.
- If there is a reload, reload during quiet moments — never in the middle of a wave.
- Prioritise the threat that will hurt you soonest, not the one that is closest or biggest. Fast enemies before slow ones, shooters before melee.
- Sound tells you where an enemy is before you can see it. Headphones help more than you would expect.
