Terms & Conditions

Robot Battle Arena: MetalBots, formerly War Bots: Robot Battle Arena and Sparkfall: Robot Combat · Asian Sparrow · Updated November 8, 2026 · Terms acknowledgement version 4

These terms cover Robot Battle Arena: MetalBots, published by Asian Sparrow, with current Android package com.asiansparrow.metalbots, and the legacy War Bots/Sparkfall edition com.asiansparrow.sparkfall. Features and availability can differ by installed version. The existing policy addresses remain available for older clients. This policy does not itself transfer saves or purchases between package IDs.

The game requires acknowledgement of these Terms and the Privacy Policy before play. If you do not agree, do not continue. Advertising consent is a separate choice.

Age and use

The game is intended for ages 13 and above. If you are under 18, a parent or guardian should review these terms with you and approve purchases where required. Unknown age or an under-13 selection restricts the app to free offline play and disables purchases, advertising initialization and network play. Select your age band accurately.

You may use the game on devices you own or control for personal entertainment, subject to these terms and store rules. Content remains owned by Asian Sparrow or its licensors. Do not unlawfully copy or sell the game, abuse payment/restoration systems, disrupt players or servers, or share content you have no right to use. Nothing here removes rights provided by applicable law.

Free access and local pilot profiles

Guests can play the first career league. An optional local pilot name opens the first three leagues. That pilot profile stays on the device and is separate from the optional Google Play Games connection available in builds that include progress backup. The game does not ask for your Google password. A verified permanent Frame Pass or Team Licence opens the remaining career leagues and currently available pass-gated modes, including Gauntlet, Rumble, Football, King of the Hill, Boss Hunt, Overdrive and Bot-Code Clash against AI. Separate-device multiplayer is Coming Soon in the current Android mobile edition and is not activated by either permanent pass. Multiplayer in compatible browser/private-room beta builds still requires compatible devices, a reachable compatible server and age eligibility.

Optional purchases

Google Play processes Android purchases. Check the actual item, localized price and payment information before confirming. Pending, cancelled or failed purchases do not grant new items. Completed purchases are verified before benefits are applied.

• Coin packs: consumable additions of 2,500, 7,500 or 20,000 combat coins, according to the selected product.
• Team Licence: permanent verified access that removes game ads, doubles daily-job coin rewards, and opens hangar bays 4 and 5. It does not double all rewards, grant the sixth bay or replace earned Engineering progression.
• Frame Pass: permanent access to the included signature frames and their four alternate builds. These builds affect gameplay; this is not a cosmetic-only purchase.

There are three coin-pack products and two permanent passes; the current catalog does not offer a recurring subscription. Both verified permanent passes also provide the all-league/mode access described above and free Pit Bay repair options. Only Team Licence removes ads, doubles daily-job coin rewards and opens hangar bays 4 and 5. Frame Pass does not include those Team-only benefits. Standard parts and upgrades outside a frame’s included build remain separate.

The earned Pro Engineering licence remains separate from the paid Team Licence. Existing playtime, level and earned-coin Engineering routes remain available. Virtual coins and items have no cash-redemption value and are not a financial account.

Supply crates and random virtual rewards

Optional supply crates spend combat coins, which can be earned through play or purchased. Crates contain randomized virtual rewards. Before confirming a crate or daily crate deal, review its displayed reward odds, eligible parts, coin-roll probabilities and any deal bonus. The odds can depend on your current inventory and are shown before coins are deducted; a changed reward pool requires reviewing the updated odds. A particular part is not guaranteed unless the displayed offer explicitly says so. These virtual rewards cannot be cashed out or redeemed for real-world money or prizes.

Restore and progress

Use Restore purchases to check eligible permanent Team Licence and Frame Pass rights with the relevant Google Play account. Network/store verification may be needed. Restore does not refund purchases, refill spent coins or recreate consumed coin packs from purchase history.

Progress is local unless you opt into an available Play Games Saved Games backup. A private journal and credit markers help complete an interrupted accepted purchase once. Erasing progress resets gameplay and coins while retaining this installation’s purchase markers and verified permanent benefits. Export/import moves gameplay progress but does not transfer paid entitlements or legal/age acknowledgement. Clearing app data, uninstalling, changing device or unavailable backups can lose local progress or recovery information.

Optional Play Games backup is available to free and paid players without a separate backup purchase. Google manages its availability, quotas, caching and synchronization. A sync request does not guarantee a completed remote upload. Restoring selects one progress history, including its saved coins and parts; balances are not combined and purchase history does not refill spent coins. Keep the correct history when devices diverge. A client-side backup is progress recovery, not an authoritative shared wallet or protection against concurrent offline spending. Turning backup off does not delete an existing Google-held save; use Google’s game-data deletion controls. Guest/offline play remains available.

For purchase problems, contact support@asiansparrow.com with the product and appropriate order reference. Refunds and remedies follow applicable Google Play policies and statutory rights. Do not repeat checkout solely because a transaction remains pending.

Advertising

Eligible free players may see a menu banner and fullscreen ads at completed-round breaks. The current policy normally waits for two eligible rounds and at least 120 seconds between fullscreen opportunities. Ads do not appear during active gameplay, countdowns or pauses. Availability and creative format depend on the provider. Team Licence removes game ads while the entitlement remains valid. The Privacy Policy explains advertising choices.

Optional multiplayer and custom content

Separate-device multiplayer is Coming Soon in the current Android mobile edition. The server-based multiplayer described in this paragraph applies only to compatible editions where the browser/private-room beta is enabled. Available offline play and Bot-Code Clash against AI do not require a player-supplied backend key or service address. Multiplayer requires a compatible server selected by the players. It may be self-hosted; the software does not promise an operated public matchmaking or hosting service. Players and server operators are responsible for network permission and server availability. Share room access carefully. Aliases, builds and displayed artwork are shared as needed for the match; use content you are entitled to share.

Updates and safety

Updates may change balance, rewards and supported features. Store, advertising and network services can be unavailable. Material changes to paid benefits will be described rather than treated as an undisclosed new purchase. The robots and combat are fictional; the game is not a guide to building or operating real combat robots.

Uninterrupted operation, compatibility with every device and recovery of every local save cannot be guaranteed. Mandatory consumer protections and remedies remain unaffected. You can stop using the game; uninstalling does not itself cancel a transaction, obtain a refund or erase provider records.

Changes and contact

Updated terms appear here with a new date. Material changes can require a new in-game acknowledgement. Questions: support@asiansparrow.com.
