Frontline Drop

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Recreate a browser-playable third-person 3D tactical extraction shooter titled “Frontline Drop,” with a dark, polished Portuguese-language interface and a simple local single-player raid loop.

Start on a full-screen lobby/setup screen over a near-black blue-gray gradient. Center a tall, rounded dark translucent panel with a thin blue-gray border and soft shadow. At the top show the gold uppercase eyebrow “OPERAÇÃO FRONTLINE · protótipo browser,” then a very large bold two-line title “Frontline Drop.” Under it show the Portuguese description: “Escolha o modo, a estação e a região. Entre na arena, pegue loot e enfrente máquinas inimigas.” Provide two mode buttons, “Squad dupla” selected in gold and “1x1” unselected in dark blue. Add four labeled dropdowns: Estação with “Verão · solo seco” and “Inverno · neve e baixa visibilidade”; País with Ucrânia, Brasil, and Estados Unidos; Mapa, whose options change with country (Ukraine: Kharkiv Industrial, Kyiv Outskirts, Donetsk Fields, Odesa Port; Brazil: Amazônia River Camp, Brasília Perimeter, Rio Hillside, Pantanal Outpost; United States: Nevada Test Range, Detroit Factory, Florida Wetlands, Colorado Forest); and Equipamento with “Carabina AR · médica,” “SMG · granadas,” and “DMR · munição leve.” Finish with a full-width gold button reading “MONTAR EQUIPAMENTO E ENTRAR,” plus small explanatory text saying this is a local demonstrative mode with game-controlled enemies and no real online multiplayer/backend.

When deploying, hide the lobby and create a Three.js-style 3D arena viewed from behind and slightly above the player, with a follow camera and a centered white crosshair. The player is an animated humanoid soldier/operator carrying a rifle, starting at approximately (0,0,9). Use a large square ground plane, atmospheric fog, shadows, a sky dome/gradient, and seasonal color changes: summer uses dry muted green/brown ground, blue-gray sky and warm lighting; winter uses pale snow/blue-gray ground and colder light with lower visibility. Build a sparse industrial tactical arena: a long dark road/lane, repeated low cover walls, sandbag blocks, scattered debris, crates, barrels, and in summer some trees. Place simple industrial building blocks with roofs in the distance. Put a glowing turquoise/green circular extraction zone at approximately (0,0,-15).

Spawn enemies as hostile humanoid “machines” (the actual implementation visually uses alternating male/female soldier character models) around the arena. In “Squad dupla” mode spawn three enemies near positions comparable to (-7,0), (7,-2), and (0,-11); in “1x1” spawn two near (0,-10) and (7,-3). They idle until the player is within roughly 20 units, then move toward the player at a slow constant speed; when within 3 units they damage the player continuously. Each enemy has two hit points and is defeated after two accurately aimed shots, then disappears and increments kills and loot count.

Scatter six small glowing gold loot cache boxes through the central lanes, each worth between 120 and 440 Russian rubles and weighing 0.6–1.6 kg. Automatically collect a cache when the player comes within about 2.1 units: hide it, add its ruble value to the backpack, increase carried weight (capped at 18 kg), increment loot, and show a temporary toast such as “Loot +240 ₽.” Also show a green extraction circle. Press E or use the EXFIL button near the circle to complete extraction; otherwise show “Vá até a zona verde para extrair.” On successful extraction display a toast such as “Extração concluída · [value] ₽ garantidos,” mark extraction “CONCLUÍDA,” and change the objective to “Operação concluída — loot salvo.” The raid has an eight-minute countdown; reaching zero ends the operation with “Tempo esgotado — operação perdida.” If health reaches zero, show “Você foi derrubado — recarregue a operação,” restore health to 100, and respawn at the starting position.

Use a simple rifle shooting mechanic: clicking the 3D view, clicking DISPARAR, or pressing F fires if ammo remains. Start with 30 rounds in the magazine; each shot subtracts one and checks enemies in a forward aiming cone/range, dealing one damage to matching enemies. Press R or RECARREGAR to immediately refill the magazine to 30 and show “Carregador trocado.” Include a visible muzzle/fire interaction if desired, but preserve the core logical behavior. Movement should support WASD/joystick through a third-person controller, with jump/gravity behavior available from the controller. The camera follows the player and aiming uses the camera’s forward horizontal direction.

During the raid, overlay a transparent HUD without blocking play. At the top, show pills for “MAPA [selected map]”, “ESTAÇÃO VERÃO/INVERNO,” “ALVOS [kills] · VIDA [hp],” and “RAID 08:00 countdown · EXTRAÇÃO PENDENTE/PRONTO/CONCLUÍDA.” At the bottom left show a dark translucent weapon card with “ARMA EQUIPADA,” the selected weapon name in uppercase (default CARABINA AR), large ammo “30 / 120,” and the hint “WASD / joystick · clique ou F dispara · R recarrega.” Beside it show a backpack card with ruble value, “Peso [weight]/18 kg,” and objective “Vasculhe caixas e alcance o ponto de extração.” On the bottom/right provide dark rounded action buttons: “DISPARAR,” “RECARREGAR,” “EXFIL,” and “SAIR.” Add centered temporary gold-bordered toast notifications for shots, loot, kills, extraction, and failures. The Sair button returns to the lobby. Keep the visual style grounded and minimal: dark navy UI, muted military arena colors, gold accent for selections and loot, turquoise extraction marker, white HUD text, rounded borders, soft shadows, and responsive layout that collapses the setup fields to one column on narrow screens.
