Testiville Tunnel

Testiville Tunnel is an underground tunnel stretching from an elevator shaft near Cliffside to a nearby desert. VGToolbox passes through it while trying to get to Testiville (from where they can get back to the VGToolbox laboratory.

Construction
Construction of the Tunnel was funded by the Preiss Association, according to signs at the entrance. An exhibit in the Tunnel Museum says that large amounts of gold were found while excavating the tunnel.

Construction of the Tunnel caused large amounts of ecological damage to the surrounding area, including the near-total destruction of the Suddenberry Jungle as well as the complete loss of the Chaom Peat Bog and the Sodden Puddle, the latter of which Buncible recalls was host to 500 endemic species (most of them leeches).

Outside Testiville Tunnel, biome incongruency was evident with the desert meeting a small patch of snowy forest. The Science Division was funding an Ecological Correction Initiative (ECI) to amend this.

Services
Testiville Tunnel contains some elementary support services supplied by Testiville Town Services, including emergency contact points, a security station with adjoining beer cooler, a first aid station fitted with four beds, and an engineering lounge.

At the time VGToolbox passed through Testiville Tunnel, the first aid station was fully occupied with patients, whose notes they read; from left to right they were: As well as the main path, Testiville Tunnel connected with Suddenberry Tunnel and Fless Shaft, although both were out of order when VGToolbox passed them due to a leak in a gravel pit that had gone unrepaired because it hadn't yet affected the engineers' lounge.

The lift leading from the far end of Testiville Tunnel to the top of Cliffside exploded when VGToolbox attempted to call it.
