| '''Low eco''' is a speedrun category in [[Jak and Daxter: The Precursor Legacy]] that restricts the player to using the lowest possible amount of eco needed to completed the game.
| | Red Sage cutscene skip is a skip in Jak and Daxter: The Precursor Legacy that allows a player to skip the cutscene that plays after opening the teleport gate in the Red Sage's lab. The skip is performed by using a pause buffer to delay the start of the cutscene once it is triggered. Jak then dies in the lava during the pause buffer and the cutscene starts after the player exits the start menu. The game attempts to play the cutscene but cannot since Jak is in a dead state. Once Jak respawns, the cutscene is flagged as watched and the game will assume the teleport gate has been opened as intended. |
|
| |
|
| The Low Eco category is known for its utilization of difficult and unorthodox strategies and techniques that aren't found in any other category. It scrutinizes the runner's true knowledge of the game and puts their abilities to the test. | | The Red Sage teleport gate needs to be opened to activate the gondola that takes Jak to Snowy Mountain. |

| == Rules == | | == Tutorial == |
|
| |
|
| The [https://www.speedrun.com/jak1ext?h=Low_Eco-Lowest&rules=category&x=jdzr18r2-38dmz3z8.z19nmr8q currently listed rules] for Low Eco are as follows:
| | == Technical == |
| <blockquote>
| |
| ''Beat the game as fast as possible while collecting as few eco pickups as possible.''
| |
|
| |
|
| ''Currently, the only eco required to beat the game are the 8 on final boss (3 blue for launchers and 5 yellow. Green eco on the second phase must be avoided).''
| | == Discovery == |
| | There are different variants of Red Sage cutscene skip, but the current method was discovered by Sultra. |
|
| |
|
| ''If eco is accidentally collected, you may load a save file to a previous state in the game, or immediately die to return to a previous checkpoint. Otherwise, you must reset.''
| | == Other Notes |
| | |
| ''No restrictions with the exception of Lava Tube Skip, which is banned.''
| |
| </blockquote>
| |
| [[Lava Tube Skip]] is banned in Low Eco. If it wasn't, Low Eco would be a slower and more boring version of [[Any%]]. The point of the category is to see how a runner manages to complete various tasks without the use of eco.
| |
| | |
| Some people question why [[Fire Canyon Skip]] isn't banned in Low Eco. With Lava Tube Skip banned, the runner needs to meet the 72 power cell requirement in Lava Tube. To achieve this, they will have to collect some power cells in Hub 1 levels. It would not make sense, and would be much slower, to skip Hub 1 with Fire Canyon Skip only to have to return to collect power cells.

| == Category Variants ==
| |
| === True Low Eco ===
| |
| The current rules for Low Eco say that the player is allowed to collect 8 necessary pieces of eco during the final boss fight. 5 yellow eco pieces to deal damage to the boss and 3 blue eco pieces to use the jump pad.
| |
| | |
| This, however, is not the true minimum amount of eco required to complete the game. By performing rocket uppercuts during the dark eco bomb segments, it is possible for Jak to get high enough so that when the bomb explodes, the fight does not end. This removes the requirement of the 3 blue eco pieces and brings the true required eco count down to 5.

| |
| | |
| === Low Eco Max% ===
| |
| Max% refers to completing as much of the game as possible while still adhering to the original category rules. In this case, Low Eco Max% refers to completing as much of the game while still adhering to the Low Eco leaderboard rules. Below is a chart of all the missions and tasks in Jak and Daxter: The Precursor Legacy that can be completed without the use of eco.

| == Other Notes == | |
| Before it was known that the [https://www.youtube.com/watch?v=WFlTSHjxZoA Mountain Pass race could be completed on the zoomer without using eco], runners found a way to complete the race on foot. They would use the [https://youtu.be/hzVE9decTco?si=bUnxE6jEwhIeeYss&t=2379 traditional method of '''first phase skip''' during the fight with Klaww to reach the center island]. When they got there, they would take damage to get down to one health. Then, they would grab the ledge to get [[Lava Walk|lava walk]] while at one health which would activate [[Ghost Glitch|ghost glitch]]. After then walking to the Mountain Pass race, they would complete the race on foot. As long as ghost glitch was active, the race's failure cutscene would not play and Jak was free to walk to the end of the race.
