Last Day is no longer being developed or supported by its developers and translators. These two, newer mods offer a similar and better experience:
S.T.A.L.K.E.R.: Last Day is a S.T.A.L.K.E.R. mod pack based on Call of Misery and version 1.4.22 of Call of Chernobyl, originally created by the Eastern S.T.A.L.K.E.R. community. It includes several addons previously unknown to the majority of the western S.T.A.L.K.E.R. community, such as MLR, which adds a lot of new characters and tasks, Outfit Marauder, adding lootable outfits on fallen stalkers, or an extended edition of Outfit Addon, adding not only outfits and helmets already present in the regular version of Outfit Addon, but also several variants of all types of apparel: regular, worn, and damaged.
Below is a flowchart detailing various projects from which Last Day derives. It is recommended to experience these first.

Fairly simple. These files need to be installed into a single directory, in order.
The mod runs standalone, meaning it should be installed on its own without being combined with Call of Chernobyl or Call of Misery.
An older version of Last Day is available here:
Here is a full list of addons and features included in Last Day:
Additionally, there are new models for NPCs and mutants, new artifacts, new mutant parts, new consumables, a simulated PDA network, stash descriptions (like in Shadow of Chernobyl), new icons, new music, new radio tracks, changes in prices, PDA tabs from Call of Chernobyl 1.5 (relations, encyclopedia etc.), and more.
Mikhail Grishin, the main developer of Last Day, announced today that development on Last Day has ceased.
This might not come as a surprise to many of you. Updates to both Last Day and its translation have been few, and Last Day Lite—another project released by the Last Day team, based on Dead Air—was never translated or even announced here. In addition, my own communication with Grishin has been sparse, and my general activity in the S.T.A.L.K.E.R. community has dwindled.
Perhaps, one day, there will be a return to the Last Day translation to finish things up on our part. Nevertheless, Last Day will remain on Mod DB unless we ever get a request from its creators to take it down, and we have a repository on GitHub for the Last Day translation—a repository that anyone can contribute to at any time.
Outside of Last Day, my team and I are working on a translation for another mod, the progress of which can be seen on our group page.
Some information about a new mod on the scene from our partners in modding.

A small WIP to fix bugs and bring more functionality to Last Day, regularly updated.
I do not own anything, found this addon on another website. Factions no longer change their attitude towards each other so fast and easily, compared to...
WARNING: MIGHT BE UNSTABLE ON SOME MACHINES. Make backup of your current "gamedata" folder or use JSGME. Playing on DX9 and/or above is highly recommended...
The translation has been updated, turning in tasks should no longer cause a crash. Moddb.com
thank you kind sir. The fix is working. Now i can enjoy Last Day fully :D
Woo. Glad to hear it.
Nice new page !
Thanks.
Ever since installing the latest translation patch, turning in any mission (new game or old save) causes an instant crash with no error message, it occasionally crashes on level changes now too.
If you still have version 0.3 saved somewhere, grab "rep_change.script" from that archive and overwrite that file. This allowed me to turn in missions without the game crashing.
I just deleted that archive a few hours ago. :(
Do you have a link or a copy you could upload?
Courtesy of Pvt.Hopscotch below:
Lines 11 and 12 in your translated rep_change.script. A comma got moved accidently causing the error.
....
["trader"] = "traders"
["zombied"] = "zombies",
}
should be:
....
["trader"] = "traders",
["zombied"] = "zombies"
}
-------------------------
Basically, all you gotta do is go into that file and move that comma. This should fix the problem, without having to use the old file.
Thanks. Fixing it now.
Thank you!
