Rivet Nova: Idle Online RPG
Play on game.rivetnova.com ↗Online RPG; account linking and optional purchases. Opens on game.rivetnova.com in a new tab. Check the setup notes below before starting.
Assemble a robot from components, choose a target and watch automatic battles turn equipment decisions into progression.
Use the workshop to equip robot components, then select a PvE target in The Hunt. Battles resolve automatically: your decisions concern the robot’s build and progression, rather than aiming or steering during a fight.
The reviewed anonymous tutorial allowed starter equipment, a successful Scrap Crawler battle, gold and experience rewards, and a component upgrade. The publisher also describes crafting, PvP, trading and guild activities; those later online systems were not independently tested.
Rivet Nova is an independently developed and self-published online robot RPG. The developer’s submission does not establish any AI development tools or engine; no such credits are assigned here.
Made by Rivet Nova.
An internet connection is required. Initial tutorial play was accessible as an anonymous pilot in the reviewed client, despite the submission describing Google sign-in as required. Expect account linking for persistent or cross-device play. Free-to-play with optional purchases and rewarded ads; physical-phone play was not tested.

Equip the starter parts before selecting an enemy. After a battle, return to the workshop and compare the equipment and upgrade options available with the resources you actually earned. A higher displayed power can be useful feedback, but it does not establish how every later matchup will resolve.
The early review reached a victory and a component upgrade using tutorial resources. It does not establish starting rewards for every new account. Keep paid upgrades separate from learning the workshop; the introductory loop can be assessed before making a purchase.
Battles resolve automatically. You choose equipment, upgrades and activities through menus.
An anonymous introductory pilot was available during review. The publisher describes Google account linking for ongoing and cross-device play; anonymous progress persistence was not verified.
The developer did not confirm AI tools. Zadely lists it as an independent RPG without assigning AI credits.
Before you play: Review covered initial PvE progression, not competitive balance, trading, guild activity, purchases or cross-device persistence. Loading and server saves can take time.
