Pre-Alpha was the main stage of development in Lumber Tycoon 2. It took place before the official Alpha Testing Stage begun. Pre-Alpha is speculated to have lasted from around the beginning of May 29, 2015 to June 15 or 30, 2015. There is not much information available about Pre-Alpha, but there is some.
Near the end of Pre-Alpha, Defaultio opened the game for public testing to find any bugs. Currently, the only known Pre-Alpha tester is EpikYummeh. EpikYummeh's name can be found within the Credits tab, on the Menu.
When Defaultio had Pre-Alpha testers, the most basic functions had already been implemented. The Stone Axe was the only axe available at the time, and the other axes came later on, as said by EpikYummeh. Vehicles also didn't have any headlights or engine sounds during this time.
The VIP Room was an area accessible during Pre-Alpha. While its true purpose is unknown, it is believed that the VIP Room was a sort of "starter-pack" for Pre-Alpha testers. The VIP Room has a near-impossible chance of spawning during Server Initialization, but it quickly disappears after. To read more about the VIP room, please click here.
The Stone Axe was an item that could be obtained in the early development of Lumber Tycoon 2. It was later replaced by the Basic Hatchet due to that fact that this axe had not been re-textured in any way. The Stone Axe was the only axe available at a point in Pre-Alpha.
The Blue-Brick Building
The Blue-Brick Building was a structure that could be found beside Wood R Us at one point during Pre-Alpha.
According to Defaultio himself, the brick building was merely a facade and could not be entered. It was used to test the growth of trees in the game and was removed shortly thereafter.
Tree growth and generation were one of the very first features that were implemented into Lumber Tycoon 2, being worked on before the summer of 2015.
In spring of 2015, when Defaultio was experimenting with tree generators and tree growth, some of his earliest trees had cylinder-shaped logs instead of regular rectangular logs. The Cherry Tree was one of the first trees made in Defaultio's generators. It is unknown if tree generators eventually evolved into the creation of Lumber Tycoon 2, or if they were just a side project along with Lumber Tycoon 2.This video was captured on July 18, 2015, during the late pre-alpha stage. This is past the existence of the Blue-Brick Building, but noticeably contains Stone Axes, conveyors in random locations, a missing safari, and land plots in odd locations.
