Those Who Remain: Game Overview & Core Loop (2026)

Those Who Remain, built by Peak Development Studios, is a co-op zombie wave survival shooter on Roblox that has stacked up over 120 million lifetime visits. The premise is exactly what it sounds like: you and your team hold out against wave after wave of increasingly aggressive undead, collect loot, upgrade your arsenal, and spend points climbing one of three perk trees to turn your character into a lean, zombie-killing machine.

Each match plays out across 15 waves. Early waves are a warm-up — standard zombies shamble toward you in manageable numbers and you'll have plenty of time to loot the map, get a feel for your loadout, and set up barricades if you're running a Craftsman build. By wave 7 or 8 the chaos ramps up noticeably: spawn counts jump, sprinters appear in bigger clusters, and you'll start seeing Boomers and special infected dropping into the mix with regularity. Waves 13 through 15 are where most squads fall apart. The enemy density hits a point where positional discipline, coordinated fire, and smart perk choices are the difference between a successful clear and a full team wipe.

The loot system keeps every match feeling rewarding even when your wave count falls short of 15. Zombies drop cash and consumables, and crates scattered around the map contain weapons, ammo, and crafting materials. Cash carries over between waves, so there's always something to spend at the buy station before the next horde arrives. The decision of what to buy — a weapon upgrade, a perk point, an extra crate — is where a lot of the game's strategic depth lives.

Every Zombie Type in Those Who Remain — Explained

Knowing what you're up against is half the battle in Those Who Remain. Each enemy type has a distinct behavior pattern, and treating a Sprinter like a Standard zombie is a fast way to get downed. Here's a breakdown of every zombie variant you'll encounter across the 15 waves.

Standard Zombies

The bread and butter of every early wave. Standard zombies walk at a steady pace, take a normal amount of damage across the board, and don't have any special mechanics attached to them. They come in large numbers but are trivially easy to kite. The main threat from Standards is when they pile up and corner an isolated teammate. Keep moving, stay in a group, and they're a non-issue through wave 5.

Sprinters

Sprinters show up in small numbers from around wave 4 onward and become a genuine menace by wave 8. They move at roughly twice the speed of a Standard zombie and will close ground fast enough to punish players who get caught reloading in the open. They have slightly less health than a Standard, which makes short bursts of accurate fire the right call — don't unload a full magazine on a single Sprinter when two shots to the head will drop them. Players running Marksman perks absolutely shred Sprinters once critical hit bonuses kick in.

Boomers

Boomers are the most dangerous zombie in Those Who Remain for inexperienced players. They're heavy, slow-moving tanky enemies that release a poisonous gas cloud either when they die or when they take body-shot damage. The gas lingers for several seconds, deals damage over time to anyone caught in it, and can completely disrupt a hold position if a Boomer dies in a choke point your team was relying on.

The counter to Boomers is simple but requires discipline: always aim for the head. A clean headshot kill drops the Boomer without triggering the gas explosion. If a Boomer is already close to a teammate, call it out and let the teammate back away before you take the shot. Running through a Boomer gas cloud to revive a downed player is one of the most common ways squads chain-fail and wipe in the late game.

Special Infected

Special infected are rare, high-priority targets that appear from wave 9 onward and increase in frequency as you approach wave 15. They come in a handful of variants — some are heavily armored and require sustained fire, others have abilities that interfere with your team's movement or vision. The exact pool of special infected types gets added to with updates, so joining the Peak Discord server is the best way to stay current on new variants that drop between major patches.

When a special infected spawns, communicate its location to your team immediately. Letting a special infected go ignored while you deal with a wave of Standards is how it snowballs into a full-squad problem. Designate one player to focus specials while the rest handle the horde — it's a clean division of labor that extends your team's effective survivability window by several waves.

Perk Trees Guide: Survivalist, Craftsman & Marksman (2026)

Those Who Remain gives every player three perk slots to fill from three distinct trees. A fourth slot is unlocked through a gamepass — worth picking up if you play regularly, but the game is completely viable without it. Your perk selections are the most important build decision you'll make, so let's go through what each tree actually offers.

Survivalist Tree

Survivalist is the defensive anchor of any Those Who Remain squad. This tree is stacked with perks that increase your max health, reduce incoming damage, speed up your revive time when downed, and give passive healing over time. The standout perk in this tree for co-op play is the revive speed bonus — in the late waves where your whole team is getting pressured, being able to pick someone up faster without getting downed yourself is massive. If your squad has a dedicated player willing to go full support, Survivalist is the tree for them.

For solo or duo runs, pairing one Survivalist perk (specifically the health bonus) with two Marksman perks is a solid generalist build that keeps you alive long enough to actually output damage.

Craftsman Tree

Craftsman perks revolve around resource efficiency and barricade mechanics. This tree lets you gather crafting materials faster, build barricades at reduced cost, repair fortifications mid-wave without burning consumables, and carry more utility items. In coordinated squads who want to hold a defensible position through the final waves, having at least one Craftsman-specced player is a strong strategic choice.

The Craftsman tree is weaker in pub lobbies where coordination breaks down quickly. Barricades are useless if your teammates run past them and pull zombies into your position. In organized Discord groups from the Peak server, though, a Craftsman player holding chokepoints can trivialize waves that would otherwise wipe a disorganized squad.

Marksman Tree

Marksman is the damage tree and it's the most popular choice across all player skill levels for good reason. Perks in this tree boost your weapon accuracy, reduce recoil on automatic weapons, increase headshot damage, and add a critical hit chance mechanic that can one-shot lighter zombies when it procs. The critical hit perk in particular is exceptional against Sprinters — it makes the "two shots to the head" approach more forgiving because a crit will drop one in a single well-placed shot.

If you're running the fourth perk slot, the most common high-end build is two Marksman perks, one Survivalist (health), and one Craftsman (resource gather). That gives you meaningful offensive output while staying self-sufficient enough to not need constant babysitting from teammates.

Wave-by-Wave Survival Strategies for Those Who Remain

15 waves sounds manageable until you're standing in wave 12 with half your team downed and a Boomer waddling toward your last standing member. Here's how to approach each stage of the match with purpose.

Waves 1–5: Setup Phase

These waves exist to fund your build and test your positioning. Don't rush — take every wave at a controlled pace, loot every crate you can reach, and use your cash to buy your first perk before wave 3 hits. Establish a hold position early. The map layouts in Those Who Remain have natural chokepoints, and finding one before the wave counts start climbing is much easier than trying to relocate under pressure in wave 9. If you're running Craftsman, start building barricades here rather than waiting until you need them urgently.

Waves 6–10: Mid-Game Ramp

This is where the match either clicks into place or starts falling apart. Sprinters appear in larger numbers, Boomers begin spawning regularly, and the cash demands of weapon upgrades start competing with perk point spending. Prioritize weapon upgrades in this window — your wave-one loadout doesn't hold up well against wave-9 enemy density. Keep a consumable heal in your inventory at all times. Players who run dry on consumables in wave 8 often find themselves at half health going into wave 9 with no recovery option, and that's a downward spiral.

Waves 11–15: Final Push

Communication is non-negotiable in the final five waves. Call out Boomer positions before shooting them. Designate your special infected hunter. If someone goes down, the whole squad moves to assist — no individual heroics that leave a teammate unrevived for 30 seconds while you chase a kill on the other side of the map. Hold your position, control your ammo economy, and resist the urge to panic-fire. Steady, aimed shots clear zombies more efficiently than spray and waste in the final waves where every bullet counts.

Weapons & Loot Guide for Those Who Remain

Those Who Remain has a layered weapon system where the guns you start with are pale shadows of what you can have by wave 10 if you spend smart. Here's what you need to know about managing your arsenal across a full 15-wave run.

Starting Weapons vs. Upgraded Weapons

Every player starts with a basic primary weapon that handles early waves fine. The damage gap between a base weapon and a fully upgraded one is significant enough that you'll want to start investing in upgrades from wave 5 onward. Don't wait until wave 10 to start upgrading — by then you're spending catch-up money instead of building an advantage. Prioritize upgrading your primary weapon over buying a second weapon until your primary hits at least two or three upgrade tiers.

Crate Loot Priority

Map crates can contain anything from basic ammo refills to rare weapon skins and high-tier guns. In the early waves, hit every crate you can see before the horde reaches you. Mid-game, be selective — a crate in a dangerous open position isn't worth the risk of getting flanked while you open it. Late game, crates with ammo are worth more than crates with weapon skins no matter how cool the skin looks. Staying alive through wave 15 with your current weapon beats dying in wave 12 while trying to loot an upgrade.

Weapon Skins From Codes

The weapon skins you unlock from codes like HALLOWS and WAVECLEAR are purely cosmetic — they don't affect stats, damage output, or perk synergies. That said, they do show up in your loadout customization and make your build look significantly better in the pre-wave lobby screen. Crate-acquired skins follow the same purely cosmetic rule. Never trade survivability for a skin unlock.

How to Get Free Robux for Those Who Remain in 2026

The fourth perk slot gamepass in Those Who Remain costs Robux, and if you're a regular player it's genuinely one of the better Roblox purchases you can make for a game you're invested in. The question is how to get Robux without spending real money on them.

Earnaldo is one of the most reliable ways to earn free Robux by completing offers, tasks, and surveys — you accumulate points and withdraw them as Robux directly to your account. It takes some time but it's legitimate and the payouts are real. If you're grinding Those Who Remain regularly and want to unlock that fourth perk slot without paying out of pocket, starting a few Earnaldo tasks while you're between gaming sessions adds up faster than you'd expect.

Beyond the perk slot gamepass, those same Robux can go toward premium crates, cosmetic bundles in the shop, or other Roblox games entirely. Earnaldo's how-it-works page breaks down the exact offer types available and how the point-to-Robux conversion works so there are no surprises.

Other Ways to Save on Roblox Purchases

If you have a Roblox Premium subscription, you get a monthly Robux stipend which stacks nicely with what you earn on Earnaldo. The Premium membership also gives a purchase bonus when you buy Robux directly, so if you ever do decide to buy some, Premium makes that go further. For games like Those Who Remain that you're playing heavily, the combination of a Premium stipend plus periodic Earnaldo earnings can cover most in-game purchases without touching your wallet directly.
