5 on-sale products
100, 200, 300, 400, and 500 Keys.
MM2 of The Locust currently has five developer products labelled from +100 to +500 Keys, while gameplay coverage also reports key pickups during escape rounds. The catalog confirms quantities and prices, not whether both are the same resource or whether purchased Keys persist. At current observed prices, the 400-Key pack has the lowest unit cost.
Each row separates a current answer from the evidence that supports it.
100, 200, 300, 400, and 500 Keys.
Calculated from the observed R$90 listing.
One Robux below the R$120 pack if separate repeat purchases are allowed.
Cross-round, cross-server, and permanent retention need live purchase/UI proof.
The 400-Key pack has the lowest unit cost in the dated catalog. The calculator can also compare exact totals when multiple purchases are allowed.

Purchase boundary: this math assumes the current interface allows separate or repeated purchases and credits the same Key balance. Confirm both in the live Roblox prompt.
Do not merge a paid product name with a round pickup. A complete trace needs before-and-after balances plus a round, server, and rejoin check.
| Check | Current evidence | Evidence still needed |
|---|---|---|
Paid pack vs round pickupUnverified | Both use Key wording in public evidence | A visible balance or objective link between them |
DeliveryObserved | Product quantities and prices are listed | Pre-purchase and post-purchase balance screenshots |
Next roundUnverified | No persistence wording in the catalog snapshot | Balance before and after a full round transition |
Server hop / rejoinUnverified | No cross-server rule is published | Same-account balances after server hop and rejoin |
What Keys buyUnverified | The product names state quantities only | A current shop spend action and resulting entitlement |
Five observed developer products sell named Key quantities. The product listing establishes the quantity and current price only.
Current exact-game coverage reports collectible keys used while players work toward escape progress. A complete first-party item table is not public.
It is not confirmed that purchased Keys and collected round items share one balance, use, or persistence rule. Check the live shop and inventory before spending.
Confirm the quantity and displayed Robux amount in the current Roblox purchase prompt.
Capture the balance before buying so an increase can be checked without guessing.
Permanent, per-round, consumable, or repeatable behavior must come from the live interface—not the product name.
Wait for the balance or receipt state to change. Do not repeat the purchase because a PRE-ALPHA interface looks delayed.
Check the full MM2 of The Locust Keys Guide state before rejoining, repurchasing, or turning one server into a permanent rule.
| Problem | Check | Next action |
|---|---|---|
| Keys did not appear | Pre-purchase balance, Roblox receipt state, current server, and whether the shop UI refreshed | Do not buy again immediately; capture the prompt and use creator or Roblox purchase support. |
| The price differs from this page | Current live purchase prompt | Use the live price, cancel if unexpected, and treat this comparison as dated. |
| A round pickup will not register | Interaction prompt, distance, objective state, and whether another player reached it | Retry once, then use the escape troubleshooting flow rather than assuming ownership or permanence. |
At the catalog prices observed through Aug 28, 2026, 400 Keys at R$90 has the lowest unit cost: R$0.225 per Key.
The observed prices total R$119 versus R$120. That comparison is useful only if the current interface allows separate repeat purchases and delivers the same Key balance.
Not confirmed. The catalog name and quantity do not prove cross-round, cross-server, or permanent retention.
