The Naturehike Opalus 3 is a 3-man, 3 season tunnel tent with a similar design to the Hilleberg Nallo 4 GT.

Nallo 4 GT tunnel design (Similar to Opalus 3)

It has 3 poles which insert within sleeves along the rainfly, bend into hoops, and then draw out into the tunnel shape - with stakes and guylines then used to secure it upright.

A 3-man inner pitches simultaneously with the rainfly, filling half the interior space, with the remaining space creating a large vestibule with 2 doors.

This shows this tent being pitched.

Tunnel tent pros:

Provides a large amount of space for the weight
Packs up compactly (less poles)
Typically has a large vestibule area

... which might suit:

Those wanting the largest backpacking tent at the lightest weight
Couples or families who prefer one, larger tent
Groups who want to minimize overall weight (i.e take fewer tents)
Those expecting lengthy periods inside their tent (e.g. persistent rain)
Those with gear that should be kept out of the weather
Those bringing dogs
Bike campers (compact packed size & can shelter a bicycle)

Other tunnel tent pros:

Lighter and more compactly stored than a similarly-sized dome tent
More weather resistant than a tarp or trekking pole tent
Consistent headroom along the center line of the tent
The vestibule area has many possible uses. e.g.:

Gear storage
Cooking
Drying clothes
Living space
Sleeping space for extra people

Some cons:

Requires stakes and guylines to stand upright - which is ot ideal on rocky or sandy ground
Less weather resistant than a dome tent - especially in swirly or lateral wind
