Hey, racing game fans, listen up! *Screw Drivers*, the physics-based vehicle-building racing game with a “Very Positive” rating on Steam, is currently free to claim. Developed by Creactstudios and published by Headup, this indie game lets players freely assemble all kinds of vehicles using the physics engine and go head-to-head on the track. Since launching in Early Access in June 2024, *Screw Drivers* has accumulated 3,871 player reviews, 87% of which are positive, earning it a “Very Positive” rating on Steam. The game is normally priced at around €7.99 (roughly NT$275), and if you claim it during this limited-time free period, it’s yours to keep forever.

Gameplay: From Screws to Race Cars
The core gameplay of Screw Drivers revolves around vehicle assembly and design. Players can use an intuitive building editor to assemble cars, trucks, tanks, planes, or any vehicle they can imagine using various blocks and mechanical parts. The game offers two power sources: fuel engines and electric engines. Players need to design their own drivetrain, transmitting engine power to the wheels through axles, gears, and suspension systems.

Whether it’s rear-wheel drive or giving all 30 wheels power, as long as the engineering is done right, the gear train will keep the vehicle running. There’s no cap on the number of vehicles in the game—4 wheels, 16 wheels, propellers, pistons, or even 50 engines can all be installed at once. This highly flexible design space lets players build everything from realistic race cars to absurd monster trucks.
The game’s physics engine is another major highlight. Every component of a vehicle affects its overall performance, and parameters such as gear ratios, suspension stiffness, and wheel grip all require fine-tuning by the player. As vehicles race around the track, the physics engine faithfully renders the operating state of each part, including effects like collisions, rollovers, and parts falling off.
The game’s track design is also worth mentioning. The tracks are spread across an island, featuring various terrains and obstacles. Players need to adjust their vehicle designs based on the characteristics of different tracks—for example, rough off-road sections require a stronger suspension system, while high-speed straight sections call for optimized gear ratios. This design makes the game more than just pure racing, adding elements of strategy and engineering thinking.

Single-player and multiplayer modes
In single-player mode, players must take on a group of royal nobles who claim to own the world’s best vehicles. Each opponent uses a different combination of blocks to activate special mechanical functions, and players must defeat them to unlock new engines, wheels, and gears. This progressive unlocking system lets players continually acquire new parts as they play, expanding their building options.
Multiplayer mode supports online and LAN battles. Players can host multiplayer servers and invite friends to race on various tracks and challenges on the island. The game also supports Steam Workshop, Steam Cloud saves, and Steam Leaderboards, allowing players to share their vehicle designs and compare scores with players worldwide.
How to claim for free
Claiming *Screw Drivers* is very simple. Players just need to log into their Steam account, go to the game’s store page, and click the “Start Game” button to add it to their library. Once claimed, the game will remain in your library permanently, even if it later becomes a paid title.
Please note that this free offer is time-limited, and the game is expected to become paid on August 20 (which should be tomorrow). Interested players should claim it as soon as possible to avoid missing out. The game is still in early access, and when the full version launches in the future, existing players will automatically receive the complete version. Fans of this type of game shouldn’t miss it.
