Games Like XCOM: Turn-Based Tactics in Your Browser

That 85% shot that misses. The soldier you tucked behind cover just in time. If those moments are why you love the series, this list of games like XCOM is for you. A quick honest note first: these are free browser games, not alien-invasion clones. Each one shares a piece of the XCOM feel, whether that is hit chances and cover, grid movement, enemies that move only when you do, or spending between battles.

What XCOM is, and what we are matching

The XCOM series began in 1994 with UFO: Enemy Unknown (released in North America as X-COM: UFO Defense) from Mythos Games and MicroProse. The best-known modern entry, XCOM: Enemy Unknown, is a 2012 turn-based tactics game developed by Firaxis Games and published by 2K. You command troops in turn-based missions against an alien invasion, then manage research, your base and your finances between missions.

No browser game copies that whole package. We looked for turn based tactics games and strategy games that capture one or more of these threads: squad movement on a grid, shot odds and cover, readable enemy turns, and preparing between fights.

1. Army Game (the closest match)

Army Game is a turn-based army men tactics game, and it is the pick to start with. You lead green plastic toy soldiers against the tan army across 12 missions, set on a bedroom floor, in a backyard, in a sandbox and on a kitchen table.

Why it feels like XCOM: Each toy can move once and act once per turn. Tap a soldier to see the squares it can reach, then tap a target to see your hit chance. That percentage drops with distance (except for the Sniper), drops by 25 for a brick and 40 for a tall block, book stack or cereal box in the way, and rises by 10 when you shoot from the hill. Tall objects block line of sight entirely.

Your squad: Riflemen, scouts, bazookas, snipers, medics and toy tanks. Bazookas do 3 damage to tanks, and the Medic cannot shoot but can stand a toppled buddy back up once per mission. Mission goals vary: topple every tan toy, capture the flag spot, hold the hill, get the Medic to the exit or survive the rounds.

Controls: Tap or click to select, move and shoot, or use arrow keys and Enter. N or Tab picks the next ready toy, E ends your turn. Best for: Anyone looking for tactics games online with real shot odds and cover.

2. Vampire Game (turn-based stealth)

Vampire Game, also called Night Fang, is a cute grid stealth game. You sneak little Vlad home to his coffin before sunrise across 12 hand-made nights.

Why it feels like XCOM: Lanterns, guards and the sky only move when you do, and the sun rises after a set number of moves. Dashed outlines show where light and guards will look after your next move, so every turn is a small risk calculation, much like checking enemy sight lines before a move. You can turn into a bat to fly over garlic and water, but each bat move uses up your meter.

Controls: Arrow keys or WASD to move, Space to wait, B to become a bat, Z to undo. Best for: Players who like the careful, overwatch-dodging side of tactics.

3. Lion Game (hex-map strategy)

Lion Game is a family-friendly savanna strategy game where you lead a lion pride across a hex map for one 40-day year. Each turn is one day, and you pick one action: move, Hunt, Drink, Rest, Mark, Roar or let the cubs play.

Why it feels like XCOM: It is about the strategic layer. Food and water drain every day, the dry season doubles thirst, and rival prides challenge your borders. You are balancing resources against a deadline, much like managing a base between missions. Best for: Players who enjoy the planning layer as much as the fighting.

4. RPG Game (turn-based party battles)

RPG Game is a compact turn-based RPG with three dino heroes. Battles are turn based and the fastest unit acts first. For each hero you pick Attack, a Skill, an Item, Guard or Run, and you exploit a Fire, Leaf and Water triangle for 1.5x damage.

Why it fits: Choosing the right unit for the right enemy is the core skill here, and leveling up unlocks new skills between fights. Best for: Players who like building a squad over a full campaign, with four bosses to beat.

5. Tower Defense (prepare between waves)

Tower Defense has you build and upgrade Blaster, Cannon, Frost and Sniper towers along a winding path to stop 25 escalating waves, including boss waves. It is real-time rather than turn-based, but you choose when to send each wave.

Why it fits: The planning between waves is the XCOM-like part. Frost slows enemies, Cannons hit groups and Snipers pick off tanks and bosses, so your build has to answer what is coming. Best for: A lighter strategy session.

6. Castle Game (fortify, then survive)

Castle Game is a castle siege game in two halves. In Defend, you spend a small budget on wood, stone, wall and roof blocks to fortify a hilltop around your crown, then watch an enemy catapult hurl boulders at it. In Attack, you take the catapult yourself and set angle and power.

Why it fits: Defend mode is all about cover and cost. Tougher blocks soak more damage, and a roof shrugs off a falling boulder. Spending fewer coins earns more stars, which rewards efficient planning. Best for: Players who enjoy setting up a position before the fight starts.

7. Chess Puzzles (think a few moves ahead)

Chess Puzzles offers 370 checkmate puzzles, from mate in 1 to mate in 3, rated easy, medium or hard. The computer answers each of your moves with its most stubborn defense. It is the purest test of the habit every tactics player needs: picturing the enemy’s reply before you commit. Best for: Short sessions, with a new daily puzzle each day.

8. Hnefatafl (asymmetric tactics)

Hnefatafl, the Viking board game also called Viking chess, pits 12 defenders trying to get their king to a corner against 24 attackers trying to trap him. You capture by sandwiching an enemy piece between two of yours.

Why it fits: The two sides play very differently, much like a small squad facing a larger force. As the defender you are outnumbered and need to find a gap. Play the 11×11 Copenhagen rules or quick 7×7 Brandubh, as either side, against the computer on three levels. Best for: Players who like lopsided, scenario-style fights.

Turn-based or real-time: which picks to try first

If you want strict turns where nothing moves until you do, play Army Game, Vampire Game, Lion Game, RPG Game, Chess Puzzles and Hnefatafl. If you like the preparation phase most, Tower Defense and Castle Game put the planning up front and then let the fight play out.

Tips that carry over from XCOM

• Check the odds before you act. In Army Game, moving one square to the hill can add 10 to your hit chance.
• Move your safest unit first. Scouting with one unit before committing the rest works in Army Game just as it does in XCOM.
• Read the enemy’s next turn. Vampire Game shows you where light and guards will look next. Use it.
• Spend with a plan. In Tower Defense and Castle Game, ask what the next wave or volley will do before you buy.

How we picked these games

Every pick is playable right here and described from what the game actually does. We did not list games that only borrow an alien theme. A game made the cut if it offered at least one real tactics thread: turns, grid movement, shot odds, cover, or planning that pays off in the next fight.
