Boom Blast Doomsday throws a lot at you early on, and if you don’t understand how the systems connect, you can waste resources fast and slow down your progress without even realizing it. The game looks simple on the surface, but progression depends heavily on how efficiently you manage upgrades, heroes, and resources.
Let’s break everything down properly so you can build smarter from the start.
Boom Blast Doomsday Beginner Guide Wiki – Heroes, Codes
Before doing anything else, it’s worth checking the small things that most players ignore.
If you open your avatar and go into the settings menu, you’ll find the gift code section, which sends rewards directly to your mail when codes are active. Even though codes aren’t always available, this is something you should check regularly because free rewards stack up quickly over time.
Right below that, you’ll find graphics and performance settings. If your phone heats up or drains battery fast, lowering visual quality and turning off environmental details makes a noticeable difference. It doesn’t affect gameplay, but it helps you play longer sessions without lag or overheating.
Heroes System
Heroes are the backbone of your account, and understanding their rarity is crucial.
The game divides heroes into S, A, and B tiers, and while you can use all of them early on, you should always aim to build around S-grade heroes. These are your long-term units, and they scale much better as you progress.
You obtain heroes through the recruit system, which uses recruit attempts. These attempts come from gameplay, unlocking land, events, and sometimes purchases. There’s also a system where you need hero shards to unlock or upgrade characters, which means even duplicates have value.
SSR heroes exist as well, but they are mostly tied to paid packs or special deals, so if you’re playing free-to-play, your focus should stay on S-grade heroes rather than chasing rare premium units.
Upgrading Heroes
Upgrading heroes seems straightforward, but this is where bad decisions can hurt your account.
When you level up a hero, you’re investing resources that are not easily refunded. There’s no simple reset system, so once you commit, you’re stuck with that investment.
Because of that, it’s important to prioritize:
- S-grade heroes first
- A-grade as temporary support
- Avoid over-investing in B-grade heroes
At the same time, starring up heroes through shards is one of the fastest ways to increase their strength. It boosts stats and increases troop capacity, which directly impacts your performance in battles.
So while leveling gives steady progress, star upgrades give bigger spikes in power.
Resource Management
Resources are everywhere in this game, but using them correctly is what separates fast progress from slow progress.
You’ll constantly receive resources from:
- Quests
- Mail rewards
- Events
The mistake many players make is using everything immediately. Instead, you should save resources and only spend them when needed for upgrades. This helps avoid losses, especially once PvP becomes active.
This ties directly into your warehouse, which protects a portion of your resources from being stolen when attacked. The higher its level, the more it protects. If you ignore this building, you’ll lose a lot of value over time.
Buildings, Troops
Combat in Boom Blast Doomsday is heavily influenced by numbers.
Your military buildings, like the shooting range, unlock stronger troop types as you upgrade them. At the same time, you should always keep troop training active because battles are often decided by how many units you have rather than just hero strength.
The hospital also plays an important role, since it allows you to recover troops instead of losing them permanently. Keeping it upgraded ensures you don’t waste resources rebuilding your army repeatedly.
Quests & Rewards
The game constantly feeds you progress through quests, and you should treat them as your main guide.
Daily quests provide steady rewards and unlock treasure chests as you complete them. Chapter quests push your overall progression forward and give larger rewards once completed.
If you’re ever unsure what to do next, checking your quest list usually points you in the right direction. It’s also one of the fastest ways to gain resources early on.
Alliance System
Joining an active alliance is one of the biggest boosts you can get.
An alliance gives you:
- Free gifts (claimable regularly)
- Help with building upgrades
- Alliance points for rewards
- Access to additional content
If your alliance is inactive or not helping you, it’s better to leave and find a new one. The game even encourages this by notifying you when your alliance isn’t active.
Timing matters too. Joining an alliance during the hours you usually play increases your chances of finding an active group, which means more help and faster progress.
PvP, Scouting & Attacking Players
Once you unlock the kingdom system, you can start attacking other players.
Before attacking, you should always scout targets to see:
- Their defenses
- Available resources
Since many players abandon their bases, this becomes a great way to farm resources if you pick the right targets.
However, your ability to scout depends on your lookout tower level. If the gap between your tower and theirs is too large, you won’t be able to gather proper information, so upgrading this building is important.
Mermaids & Extra Rewards
As you progress, you unlock mermaids, which are essentially passive resource generators.
You can send them on missions to bring back items like:
- Lumber
- Special resources
- Items that increase affinity
While this system isn’t the main focus, it adds steady passive income, which helps over time.
Some battles, especially building destruction modes, rely on how you aim your attacks.
Instead of always aiming high, sometimes a lower, more direct trajectory deals more damage. In certain situations, hitting structural weak points or aiming between sections can collapse entire buildings in one shot.
It’s a small detail, but learning this makes clearing stages much easier.
