Doomsday Last Survivor 3rd Anniversary Event Guide

Shortcut

First of all, happy 3rd anniversary to Doomsday Last Survivor! Looking forward to the 4th anniversary.

With that out of the way, below are some information about Doomsday Last Survivor 3rd Anniversary event, based on my gameplay quite recently.

Note that there are 2 main events happening in 2 different places. Web event and in-game. Each with their own to do list.

Web Event

In order to access the web event, you can click this or copy paste this link into your browser — https://dls.igg.com/3rdanniversary/

Home Tab

This will be the main screen when you first land on the website. There are some things to do here.

Find the cake on this page and click it.

Rewards below will be unlocked and sent to your in-game mail. Note that this can be redeemed only once. Take it and go.

(Optional), if you are keen to listen to anniversary soundtrack, can click this. (Special thanks to Vendetta from region 36, I wonder if he was a composer).

Anniversary Fiesta

This screen simply showing information about the in-game event. It is good to know, though no rewards can be found here. Skip.

Events

Here is where the goodies are. It is broken down into 2 side events.

Billion Gem Giveaway

Event duration: 2026/03/13 – 2026/03/31 (UTC)

During the event duration, simply complete in-game mission and come here everyday.

Missions you need to complete:

Reach 80 daily mission AP –> Just use auto complete in-game
Visit event page for first time everyday –> just go the website and click claim
Share the event page for the first time everyday –> click share, exit, and click claim

Upon successful completion, your point will increase by 1 for each mission (total 3).

Remember that you need to reach 30/30 to be eligible for gems giveaway (as you can see mine is currently on 12/30).

When the distribution period starts (which on scree, is in 12+ days), the total gems shown on screen will likely be distributed towards those players who have successfully reach 30/30.

So make sure you complete this mission by then.

Anniversary Gathering

Inside, there will have 2 tabs (Form Team, and Lucky Draw).

Form Team

Event Duration: 2026/03/13 – 2026/03/31 (UTC)

In my opinion, this event can be quite tricky.

Basically you need to gather 2 other teammates to form a group, and based on their account ID, will determine the number of rewards you receive.

There are 5 conditions that you need to satisfy, and their associated rewards.

If you prefer the text,

Form a team of three members
Team has ≥ 2 members and last digit of every team member’s IGG ID adds up to an odd number
Team has ≥ 2 members and any team member’s IGG ID contains a multiple of 3
Team has ≥ 2 members and last digit of every team member’s IGG ID adds up to ≥ 1
Any team member has an IGG ID ending with 3

I believe the most important criteria is #5, as finding IGG ID ending with 3 can be a hassle as the event has been around for a few days already.

For each criteria you satisfy, you will get 10 tickets for Lucky Draw (explained below). So make sure to get all 50 tickets.

Lucky Draw

Earn Prizes Duration: 2026/03/24 – 2026/03/31 (UTC)

Here is where you can use the ticket from “Form Team” mission.

Depending on your “success” of completing the above conditions, you will receive 10-50 tickets. Here you can consume your acquired tickets for various rewards.

The grand prize of this roulette is 100k gold, and only 2 available from the pool. So be quick when the wheel is unlocked.

Only 6 people will leave this event feeling like oil tycoons with that amount of gold.

Annual Plan

The last tab just some information about developer’s future plan. Looks ok to me, and do read if you are curious. Else can skip.

In Game Event

Event Duration: 2026/03/15 – 2026/03/23 (UTC)

Note that the in-game event will finish earlier vs web event counterpart by 1 week.

When you open the game, there will be a new icon for the “Anniversary Fiesta” event. Inside will have various sections, each with their own things to do and freebies to take.

Just remember to click that red circle (with number) when it appears.

Fiesta Hunter

The first impression I have when seeing the above screen for the first time — great, here we go again with the 1000 zombie killing spree. Followed by a prompt that Back Alley Doctor event is currently ongoing, plus in such event like this, we will have hivemind rally mission.

Note that this week you probably will open up your stamina bag quite a lot. Hope you save enough resources for this.

Ok, back to the event.

The objective here is that you need to do the following actions during the event period in order to get Anniversary Fiesta Gift Box.

Complete Radar Station
Defeat Zombie (1000 limit)
Resource Gathering

This Gift Box can later be opened (via your bag) to get both Fiesta Ticket and/or Light Stick.

Both of which, are needed for the other sections of the event.

Fiesta Concert

Stella can find finally find her place to sing

Here you need to use the obtained Light Stick.

You have 2 options, whether using 1 or 10, generally picking 10 just save more time instead of doing 1 at a time.

The maximum level is level 25. Once you reach past this, there will be another milestone that will appear. it is up to you if want to chase past this. If you max everything without paying, is good enough to get the 1st milestone. Any additional will need to pay money.

Do remember to buy the middle tier for 7000 gems. (Not to worry, if you manage to reach level 24, you will get those 7000 back).

Unlocking level 15, 20, and 25 will enable Lucky Cache (of which you can share to others) for various rewards. I personally will use these at the last day of the event. Since you have cap on how many lucky cache you can obtain per day. Let other finish theirs first.

Fiesta Concert Ranking

If you have spare gold or money, you can go buy some packs and participate in this competition.

Note that only top 10 top scorer by the end of the countdown is eligible for permanent skin, the rest (top 11-100) can only borrow for limited time only.

Anniversary Gift

If you are a spender, you can get many freebies from here based on your spending (capped at 18,500). Skip this if you are F2P.

Anniversary Challenge

In the next 7 days, new missions will be unlocked. Complete those missions to get various rewards.

Quite straightforward like similar event in the past.

The only comment I have here, is that for you to wait patiently till day 7 so you can get the most out of excess resources, to prevent unwanted things to happen.

Example Scenario

On day 2, say the game put building might increase.
You need speedup to fasten your upgrade, so you use many.
Now, say on day 4, there is a mission to use speedup.
The speedup you use on day 2 will be wasted and not be counted. Hence you need to use other form of speedup.
— versus —
You wait until day 7 when all missions unlocked, do just enough without spending a lot of rss
Say now you want to increase your building might, with the same amount speedup like the above, you can tackle multiple missions at the same time. Thus generating more rewards.

Fiesta Score

You can trade the premium currency (Fiesta Coin) with various rewards here. You can check with your R4/R5 on what good item to get here. Personally I will pick Skin Voucher.

7 Day Fiesta

Simply login and get various rewards, nothing else to say

Festival Prep

This is the single most painful part of the whole event.

Here you need to gather 4 other members and build a statue. And when everyone finished their statues, the top right max level rewards will be unlocked.

For one statue, you will need roughly 76000 points.

That means you and your partner, each needs to chip in 38000 points.

You need to use Fiesta Ticket to get points, where minimum points you will receive is 60.

Looking at past events, the game can be quite stingy for players to obtain points.

In the past, even after killing 1000 zombies, doing everything in the mission, kill all the mini bosses, I can barely get enough points to have all statue up. The rest I need to do some rss farming.
Not to mention if any of your team members is missing in action after joining, you can kiss bye to the max level rewards.

Some comments about this event (in case developer read)

Please re-add hivemind as another way to obtain event drop.
Killing 1000 zombie is quite hard as it is, especially for newer player. Please add some leeway on point multiplier at least so many can get the max level rewards.
