What online combat games are, and how they actually work
"Online combat game" is a loose label that covers a very large slice of modern gaming. This page pins the term down, describes the main forms it takes, and explains the machinery underneath — the parts that shape how the game plays and how it earns.
What the term means
An online combat game is one where the central activity is simulated fighting, played over the internet against or alongside other people in real time. That covers a wide range: fast arena shooters, large-scale battlefield games, tactical squad games, and vehicle-based games where the fighting happens through aircraft, tanks or ships rather than a soldier on foot. What unites them is not the setting but the structure — you connect to a shared session, you are matched with other players, and the outcome depends on live decisions made by real people rather than a fixed story.
The distinction from a single-player game matters for a few practical reasons. Because other people are involved, there is a social dimension with its own risks, from unpleasant chat to organised scams. Because the game runs on the provider's servers, it can change after you start playing — rules, prices and content are all adjustable. And because these games are usually designed to be returned to over months, the way they hold attention and prompt spending is built in from the start, not bolted on.
The main types you will meet
It helps to sort the category into a few broad shapes. The lines blur, and many games borrow from more than one, but the shapes describe most of what is on offer.
Infantry shooters
The most familiar form: you control a single character on foot and the game is about aiming, movement and positioning. These range from quick, casual matches to highly competitive formats with ranked ladders.
Vehicular combat games
Here the fighting is done through machines — aircraft, helicopters, tanks, warships — and much of the depth comes from the differences between vehicles and the physics of using them. War Thunder, which we describe separately, sits in this group. These games often lean towards simulation, rewarding patience and knowledge over pure reflexes.
Large-scale battlefield games
Dozens of players share a single large map, sometimes mixing infantry and vehicles, with objectives that require coordination. The appeal is the sense of scale and the way individual actions add up to a bigger fight.
Tactical and squad games
Smaller teams, slower pace, higher stakes per decision. These reward communication and planning, and they tend to attract players who prefer thinking to twitch.
Why the type matters to you
The type sets the tone, the time commitment and the community. A casual arena shooter asks little; a simulation-leaning vehicle game or a tactical squad game asks for study, practice and often a headset. Knowing which you are installing saves the disappointment of expecting one thing and finding another.
How live multiplayer actually works
When you join an online combat game, your device is not running the whole game by itself. It talks constantly to the provider's servers, which hold the authoritative version of what is happening and keep every player's screen roughly in step. This is why a stable internet connection matters, and why "lag" — the delay between an action and its effect — is a common frustration rather than a fault in your device.
Matchmaking is the system that decides who you play with and against. It usually tries to group players of similar skill or progress so that matches are competitive rather than one-sided. Understanding that matchmaking exists explains a lot: why your early games feel gentle, why difficulty seems to rise as you improve, and why the same game can feel very different to a newcomer and a veteran.
Because the session is shared and social, most of these games include text or voice chat. That is where the human side of the category lives — cooperation and camaraderie, but also harassment and unwanted contact. Australia's eSafety Commissioner publishes practical guidance on handling online abuse and provides a route to report serious cases, and most games offer their own mute, block and report tools that are worth learning early.
Progression, and why it exists
Almost every online combat game gives you something to work towards: levels, ranks, new equipment, cosmetic items, or a "battle pass" that hands out rewards as you play. Progression is not decoration. It is the main reason people return day after day, and it is deliberately paced so that the next reward always feels within reach.
None of that is sinister in itself — a sense of getting somewhere is a large part of why games are enjoyable. It becomes worth watching when progression is tied to money, because the same design that makes free play satisfying can also make paid shortcuts tempting. A game may let you unlock a vehicle through many hours of play, or through a purchase that skips the wait. That is a legitimate choice to offer; the point is to recognise it as a choice, and to make it deliberately rather than in the heat of a session. We look at that mechanism closely in our guide to in-game spending.
How these games earn money
Understanding the business model removes most of the surprises. There are three common approaches, and many games mix them.
| Model | What you pay up front | Where the money comes from later |
|---|---|---|
| Paid up front | A one-off price to buy the game | Sometimes add-ons or expansions; sometimes nothing further |
| Free-to-play | Nothing to download and start | Optional items, upgrades, cosmetics, currencies and passes bought over time |
| Subscription | A recurring fee | The ongoing fee itself, sometimes plus optional extras |
The free-to-play model is the most common in this category, and the most misunderstood, because "free" describes only the front door. The full picture — how a game can cost nothing to start and still be highly profitable — is worth its own page, which is why we cover free-to-play games in detail.
What to check before you start
A few minutes of checking before you install saves most later regrets. None of this requires special tools.
- Confirm the platform. Some games are desktop-only (Windows, macOS, Linux) and will not run on a phone or console, so check the requirements on the provider's own page.
- Look up the classification. See how the game is classified in Australia and what that marking means, especially if a younger player is involved.
- Read the model. Is it free-to-play, paid or subscription, and what is the optional spending like once you are in?
- Set up the account carefully. Use a strong, unique password and turn on multi-factor authentication if it is offered.
- Decide your limits in advance. A rough time and money budget, set before the first session, is far easier to keep than one invented mid-game.
What to watch out for
Be wary of any site that is not the game's own provider offering "free" downloads, giveaways of premium currency, or account "boosts". These are a common vector for scams and malware. When in doubt, start from the provider's official page, and check the current warnings at Scamwatch.
Key terms, defined
- Matchmaking
- The system that groups players into a match, usually by skill or progress, so games are reasonably balanced.
- Progression
- The levels, ranks and unlocks you earn by playing, designed to give a continuing sense of advancement.
- Free-to-play
- A model where the game costs nothing to download and start, with money made from optional purchases later.
- Battle pass
- A tiered set of rewards, often seasonal, unlocked by playing and sometimes by paying to progress faster.
- Virtual currency
- An in-game token bought with real money and spent on items, which can make the real cost of a purchase harder to judge.
