# Make a game like Counter-Strike
> The Summer pieces behind a competitive team shooter like Counter-Strike or Valorant: 5v5 matchmaking, instant movement, fair hits and ranked play.
A tactical shooter lives or dies on fairness. Two teams of five start level,
every player's movement feels instant, a shot that looked like a hit counts as
a hit, and a win moves your rank. Summer gives you each of those pieces. This
page shows how they fit together.
## The pieces you need
Your server runs the rules; every player runs the same game.
A ranked 5v5 queue, matched by skill, with an accept prompt.
Friends queue together and land on the same team.
Each player's own character moves the moment they press a key.
Shots are checked against where targets were when the player fired.
Rounds, the bomb, the score and each player's money, kept by the server.
The server decides who won and closes the match.
A rank that moves after every match, and a top 50.
Talk to everyone in the match.
Weapon skins and characters players own and show off.
## How it fits together
Friends form a party and press Play together. Matchmaking builds two even
teams of five and asks everyone to accept. Summer starts a server for the
match, where your rules run the rounds. When the last round ends, the server
reports the result, and every player's rating moves.
## Plan my game
I'm making a tactical team shooter like Counter-Strike in Summer. Read my
project and plan how to build it with these Summer skills, in this order;
if you don't have them installed, find them in the Summer library:
1. `multiplayer` and `multiplayer-project`: the server and client scenes and
a first Local Play run.
2. `multiplayer-movement`: each player moves their own character instantly.
3. `multiplayer-state`: rounds, the bomb, the score and each player's money.
4. `summer-matchmaking`: a ranked 5v5 queue with an accept prompt.
5. `summer-match-results` and `summer-leaderboards`: winners, losers and ranks.
6. `summer-parties`: friends queue together.
For each step, tell me what changes in my project and what I'll see when I
test it. Don't change any files yet.
## Build the signature features
### Rounds and a buy phase
In my Summer project, add round-based play like Counter-Strike: a short buy
phase, a round timer, and a match won by the first team to \[N] rounds. Use
the Summer `multiplayer-state` skill; if you don't have it installed, find it
in the Summer library.
* The server owns the clock, each player's money and the round winner.
* Players ask the server to buy; the server checks they can afford it.
* Everyone sees the same round number, timer and score.
Read my project first and tell me what you'll change. Then test it with Local
Play and tell me what you saw.
### Shots that feel fair
In my Summer project, make shooting feel fair at real-world ping: when a
player fires, the server checks the shot against where the other players were
on that player's screen. Use Summer's lag-compensated hit checks
(`SummerNetworkHitHistory3D`) together with the Summer `multiplayer-state`
skill; if you don't have it installed, find it in the Summer library.
Read my project first and explain how my weapons fire today. Then test it
with Local Play at 100 ms of emulated ping and tell me what you saw.
