I checked every top guide so you don’t have to. Survive a Million Monkeys is a Roblox co-op horde shooter. Cash buys upgrades during a run, while Gems unlock permanent classes and weapons. Free codes can give you a quick Gem boost, and Bomber and Engineer are the classes I’d chase first. Here’s the fast version:
| Topic | Quick Answer |
|---|---|
| Active codes | MONKEYS, SURVIVE (1,000 Gems each) |
| Best class | Bomber (120,000 Gems) |
| Budget pick | Engineer (30,000 Gems) |
| Weapon goal | Unlock a Tier 4 heavy weapon |
| In-run keys | V = weapon tier, C = health, Q = ultimate |
| Code | Rewards | Status |
|---|---|---|
| MONKEYS | 1,000 Gems | Active |
| SURVIVE | 1,000 Gems | Active |
| 1MVISITS | 10,000 Gems | Reported, unverified |
| 5MVISITS | Gems (amount unconfirmed) | Reported, unverified |
Expired codes: none listed by any guide yet.
Codes aren’t case-sensitive, so spelling is what matters. Some guides print “1MVISIT”, but most list 1MVISITS. If one fails, you’ve probably already used it, since each works once per account.

Classes replace your G, X and Q skills. Gem prices below are an October snapshot, so check your Classes menu before spending.
| Class | Unlock | Standout Skills |
|---|---|---|
| Survivor | Default | Grenade, Barricade, Airstrike |
| Medic | 15,000 Gems | Healing Pod, Code Blue team heal |
| Engineer | 30,000 Gems | Auto-turret, Overclock |
| Juggernaut | 75,000 Gems | Ground Slam (60 damage), Brace (-30% damage taken) |
| Bomber | 120,000 Gems | Short Fuse (200 damage), Blast Dash |
| Outlaw | Gunslinger Bundle (899 Robux) | Ricochet (200 damage) |
Weapons come in four tiers: handguns, shotguns and medium-range guns, assault rifles, then heavy weapons. You have two ways to climb:
Since the handgun phase is short, put your Gems into a higher-tier hub weapon first. One guide reports a progression of Deagle, P90, SCAR, then Grenade Launcher. I couldn’t confirm that list elsewhere, so check the Weapons menu. You’ll usually afford Tier 4 around wave 20.
MONKEYS and SURVIVE give 1,000 Gems each. 1MVISITS (10,000 Gems) is reported but unverified.
Finish the tutorial first. Also check the spelling, and remember each code works once per account.
Bomber for raw damage and Engineer for budget turret defense.
Gems come from the monkeys and waves you clear each run, plus codes.
