Tunnel Tests
The Tunnel Tests refers to unfinished test versions of Tunnels from Nowhere, a Kjolt project in early conceptualization and a successor to Rodney's Tunnel. It serves both to port over and improve existing features and to test new ones, such as NPCs and other interactive entities, all within an updated version of the same engine. Due to the unfinished nature of the Chinook engine, the tests are merely that and will likely have to be ported again in the case of a future stable, finalized version.
These tests also serve for experimental purposes beyond Tunnels from Nowhere and the Rodney's Tunnel remake, such as when the gopher aliens are seen in "gophers on a corn tortilla" as enemies or the ominous, foggy level in the video "terrible tunnel".
