Explorer

"This vehicle has been designed by our best Vehicle Designers™ to allow for easy, fast and safe exploration of alien territories. *Wifi hotspot not included."

- Caterina Parks's assistant Steve

The Explorer is an all-terrain vehicle developed by FICSIT Inc.. It has better drifting than the truck, and appears to also be faster than the truck and tractor. The explorer has a "grappling" ability, allowing it to latch onto terrain in order to climb up to hard to reach areas. The explorer has 24 inventory slots.

Speculation
The Explorer appears to have two seats, prompting the idea that these may be used to transport multiple engineers.
