The latest update for Roblox: A Desert delivers one of the biggest overhauls yet — featuring the SMZ microcar, NPC traffic, new weapons, interactive items, and even custom audio support. This guide covers every new addition in detail, from vehicle mechanics to item performance and hidden features.
1. SMZ Microcar Overview
General Info
- Category: Vehicle
- Type: Microcar (based on real SMZ model designed for disabled drivers)
- Seats: 1 by default (can add a 2nd seat manually)
- Engine: Two-stroke rear-mounted engine
- Transmission: 4-speed gearbox
- Fuel Capacity: 12 L
- Oil Capacity: 3 L
- Radiator Capacity: 4 L (same as Lada)
The SMZ is a small, lightweight car meant for compact travel. While it’s not designed for speed or heavy hauling, it introduces several new mechanical details not seen in previous vehicles.
Key Features
Pedal-based control: Unlike older vehicles that used levers, the SMZ now uses pedals, improving realism.
Detachable roof: You can manually remove the roof to turn it into a convertible, though it can glitch or get stuck.
Rear engine: True-to-life placement, with visible two-stroke mechanics when you open the rear hood.
Front battery compartment: Battery installation point located under the front trunk area.
Dashboard and Controls
Horn button: Added to steering wheel (right side).
Hazard light switch: Active and functional.
Headlight button: Currently bugged (does not toggle).
ACC mode: Must be on for dashboard buttons to respond.
Performance Test Results
Base Top Speed: 109 km/h
Acceleration (0–100 km/h): 11–12 seconds
Fuel Usage (10 km test): Consumed 2.3 L of gas and 1.1 L of engine oil
Radiator Loss: 0.3 L
Fuel and oil consumption are very high for its size. The SMZ is stylish but inefficient — likely to be buffed in a future patch.
Upgraded SMZ (with Gearbox Pro)
Replacing the stock gearbox with Gearbox Pro dramatically improves performance:
- Top Speed: 145 km/h
- Acceleration: Faster and smoother gear shifts
This mod transforms the SMZ into a surprisingly agile microcar, though fuel consumption remains heavy.
2. Rocket Launcher Weapon
Category: Ranged Weapon
How to Use:
- Load Rocket Ammo into the launcher’s muzzle.
- Fire manually — does massive explosion damage.
Damage Test Results:
- Vehicles: Instant destruction (parts detach completely).
- Zombies: Instant kill; ragdolls and launches targets.
Verdict: The rocket launcher is one of the most powerful weapons ever added, easily replacing the need for the rocket turbine when dealing with zombies or vehicles.
3. Big Trailer Vehicle Add-On
Category: Trailer
- Much larger than standard trailers.
- Can store significantly more cargo.
- Fully compatible with most cars (tested on Lada and SMZ).
- Does not slow down vehicles during towing.
Verdict: A major quality-of-life improvement for haulers and builders who need mobile storage solutions.
4. NPC Traffic System
New Feature: AI-controlled cars driving along the roads.
- NPC cars appear randomly on highways and small roads.
- Movement is not perfectly smooth; they sway slightly.
- You can pit maneuver them — they recover automatically by returning to the road.
- Explosion interaction: Blowing up NPCs causes them to scream and die.
- Vehicle Interaction:
- Player cannot steal NPC vehicles.
- Can open all passenger doors, but driver’s door is locked.
- NPCs will stop and brake intelligently if you block them.
Verdict: While buggy, this is one of the first functional traffic systems in a Roblox survival game, adding realism and liveliness to the desert world.
5. New Interactive Items
Boom Box
- Functions as an audio player.
- Requires speaker and battery installation.
- Insert a CD or play music using Audio ID.
- Gamepass: Boombox Plus (15 Robux) allows custom music through Roblox IDs.
- Entirely cosmetic, not pay-to-win.
Verdict: Adds atmosphere and creativity to camps or roleplay builds.
Sword (Egyptian Style)
- New melee weapon, similar damage to Axe (3 hits to kill a zombie).
- Functions as a light secondary weapon for close combat.
Cement Bag
- Heavy decorative object, becomes difficult to lift due to weight simulation.
- Used primarily for construction aesthetics.
Plank 7
- Small square plank for detailed structures.
- Ideal for miniature sculptures or decorative builds.
Secret Item: Masha Doll
- Hidden sandbox item named “Secret”.
- It’s a Masha and the Bear-themed doll, with a veil and bear head.
- Purely decorative and collectible.
Food Items
- Kulbasa: Large sausage-style food item; fully edible.
- Kebab: Turkish food; restores hunger.
Verdict: Minor additions that improve immersion and variety in survival gameplay.
6. Sleeping System and Beds
- New Item: Bed
- Used to sleep and skip night.
- Cannot sleep during daytime.
- Once asleep, press E to wake up and automatically switch to daytime.
Note: The sandbox weather/time menu is currently disabled, but this bed mechanic lets you bypass that limitation.
7. Siren Device
- Functions as an attachable police siren for vehicles.
- Emits red/blue flashing lights and authentic siren sound.
- Ideal for roleplay or convoy builds.
Verdict: A fun addition for police-style roleplay setups or convoy signaling.
8. Tornado and New Building
- Tornado Event: Rare occurrence capable of damaging buildings.
- New Building: A telecommunications tower, currently very rare to find.
- Future updates may expand this with additional destructible structures.
The A Desert update is a major leap forward for sandbox immersion. From the quirky yet detailed SMZ microcar to AI-driven NPC traffic and destructive rocket launchers, this patch deepens every aspect of the experience. It’s not perfect — minor bugs like the SMZ headlight issue and AI pathing remain — but overall, this update brings the game closer to a full-fledged open-world simulator with real mechanical depth.
