Mortuus Weapons Guide: Guns, Ammo, and Ascension Tips

What Weapons Can You Get in Mortuus?

An empty magazine makes a crowded hallway feel a whole lot smaller. Mortuus weapons matter because buying guns, replacing ammunition, and upgrading your damage all compete with the points you need to open the map. Learn how Mortuus weapons fit into that economy, and you can plan your next purchase before the horde forces the decision.

Mortuus features more than 30 guns, wall purchases, a Mystery Box, and Gun Ascension upgrades. Its procedurally generated maps change the placement of weapon access and other facilities between runs, so memorizing one shopping route only gets you so far.

The demo includes the following weapon names among its arsenal:

Weapon	Demo details
UMP	Available as a purchasable weapon during early play
MP7	Appears among the weapon options
G36	Appears during demo runs
M-16	Encountered while exploring the map
Tommy gun	Available during demo play
Tech 9	Can appear from a random weapon purchase
Spaz Shotgun	Obtainable from a wall purchase or the chute-style random weapon mechanic

These examples give you a starting point for recognizing guns as you explore. They are a partial roster, and their names alone do not tell you how a particular run’s upgrades will affect your choice.

Judge your next purchase against the problem in front of you. Check your remaining ammunition, the points required to keep exploring, and the upgrades already supporting your current gun. Keep a functioning weapon while you work toward the next part of your build.

How to Get Mortuus Weapons: Wall Guns and the Mystery Box

You have two central ways to acquire Mortuus weapons during a run: buy a gun from the wall or spend points on the Mystery Box. Both draw from the same points you use to buy doors, clear debris, and purchase other improvements.

That shared budget makes every weapon purchase a progression decision. Spending everything on another random gun leaves fewer points available for reaching the power switch or opening a route through the map.

Acquisition method	How it works	Detail to remember
Wall gun	Purchase the weapon displayed at a wall location	Matching wall locations also sell ammunition
Mystery Box	Spend points to receive a random weapon	The result is a gamble
Chute	The demo’s chute-style weapon dispenser provides random guns	It can provide weapons such as the Spaz Shotgun

Check Wall Purchases Before Gambling

Inspect nearby wall weapons before spending points on a random roll. Compare the visible option with your current ammunition situation and the amount of exploration you still need to fund.

When you buy a wall gun, remember its location. That purchase point has another use later: replenishing ammunition for the matching weapon.

Avoid building your entire plan around finding the same gun in the same room next time. Each run rearranges rooms, corridors, courtyards, and important facilities.

Give Each Random Purchase a Purpose

Use the Mystery Box when you are willing to accept an unpredictable replacement. Set aside the points needed for your next objective before rolling again.

A random purchase can introduce a different weapon, but it also spends resources without letting you choose the result. If your current gun still handles the round, inspect the map and your upgrade options before committing more points.

With Mortuus weapons, access matters alongside firepower. Keep track of what you can buy now, where you can replenish ammunition, and which doors still separate you from power.

How to Refill Ammo and Avoid an Empty Gun

Ammunition deserves attention before the last magazine. Mortuus lets you buy ammunition from the matching wall weapon, while power-ups and a round-end ammunition card provide additional ways to replenish your supply.

The crucial detail is the matching weapon. Return to the wall location for the gun you need ammunition for, rather than expecting any wall purchase to refill whatever you are carrying.

Ammo option	What it provides	Requirement or limitation
Matching wall weapon	Purchasable ammunition for that weapon	Find the corresponding wall gun
Max-ammo power-up	An ammunition refill	Collect the power-up when it appears
Round-end ammunition card	Bullets returned after a round	Select the card when offered
Infinite-ammo power-up	Firing without consuming ammunition while active	Depends on obtaining the power-up

Plan the Refill Before You Need It

Check your ammunition while the round is still manageable. Locate the matching wall purchase and consider the doors, stairs, and narrow passages between you and that refill.

Keep enough points available to respond to an ammunition shortage. A weapon upgrade cannot help you shoot an empty gun, and a distant purchase becomes harder to reach with zombies closing in.

Use barricade repairs to earn additional points when you have room to work. Repairing barriers contributes to your spending pool, which can help fund weapons, ammunition, or further exploration.

Account for Your Ammo Upgrades

When the round-end ammunition card appears, compare it with the other offered upgrades. Choose it when ammunition supply is the immediate problem you need to address.

Use infinite-ammo opportunities to attack without draining your reserves, but check the effect before committing to a prolonged fight. Resume watching your ammunition once it ends.

Mortuus weapons become much easier to manage when refilling is part of your route. Revisit useful wall locations as you explore, and check your supply before starting another push into unopened rooms.

How Gun Ascension and Weapon Upgrades Work

Mortuus weapons develop through several connected systems: Gun Ascension, the upgrade draft after each round, purchasable perks, and elemental effects. Each changes a different part of your survival plan.

Gun Ascension lets you bring a weapon to an altar and choose how it becomes stronger. You can repeat the process as many times as you can afford. Finding the altar therefore creates an ongoing place to invest in a gun you want to keep using.

Upgrade system	What it changes or provides	How you access it
Gun Ascension	Strengthens a gun through selectable improvements	Bring the weapon to the altar and spend points
Round-end draft	Offers one upgrade choice after each round	Complete the round and choose from the draft
Perk machines	Provide purchasable survival improvements	Find machines around the map
Elements	Add elemental variety to combat	Mortuus features five elements

Find Power While Developing Your Weapon

Power is an important exploration objective. The demo includes upgrade facilities that require electricity, including Ascension.

Open doors and clear debris while looking for the power switch. Remember useful machines and the altar when you find them so you can return after restoring power.

Do not spend your entire budget simply because an upgrade location is nearby. Check whether it is operational and preserve the points needed to continue your search.

Match the Draft to Your Current Needs

The round-end draft includes choices affecting weapon damage, head damage, reload speed, movement, and points earned. Select an upgrade that addresses what is making the current round difficult.

If reloads keep interrupting your attacks, take reload speed when offered. If you need more purchasing power for exploration and upgrades, consider a points-earned choice. If your gun requires too many hits, choose a damage option when it appears.

Think through a weapon-specific upgrade before selecting it. When the choice applies to a pistol you intend to replace, weigh that short-term benefit against another available improvement.

Keep Gun Ascension and the round-end draft in the same plan: invest points in the weapon you intend to retain, then use draft choices to support the demands of the run.

Build a Weapon Plan Around the Map and the Horde

Mortuus weapons operate inside a changing arena. Some zombies chase directly, while others cut you off or take different routes. Later threats include the Juggernaut, Lope, and ceiling-traveling Skitter.

That behavior makes positioning part of weapon management. A reload becomes dangerous when an enemy reaches your flank, and a useful purchase becomes difficult to access when the approach fills with zombies.

Start With Access and Ammunition

Follow this sequence as a flexible checklist:

1. Inspect available guns. Check nearby wall purchases and your current ammunition.
2. Keep funding exploration. Reserve points for doors and debris removal.
3. Remember refill locations. Track the wall purchase matching your weapon.
4. Search for power. Open access to facilities that require electricity.
5. Develop the gun you intend to keep. Use Ascension and relevant draft choices.

Adapt those priorities to the room you are in. If ammunition is nearly gone, address it before spending on an optional improvement. If your weapon is functioning well, continue opening the map toward power.

Use Dismemberment Deliberately

Shooting zombie legs can turn enemies into crawlers. Use that mechanic when you want to slow an approaching enemy, then keep checking the space around your feet as you move.

Powerful guns can punch through enemies. Look for firing angles that place zombies behind one another, while keeping your escape route in view.

Keep watching above you once Skitters enter the fight. Their ceiling movement adds another direction to check while aiming, reloading, and approaching a purchase.

Make Your Next Purchase Solve Something

Before spending points, identify the immediate need:

• Buy ammunition when your current gun is running dry.
• Purchase a replacement when you need another usable weapon.
• Open a door when exploration is blocking access to power.
• Visit Ascension when you want to strengthen a gun you plan to retain.
• Choose a draft upgrade that supports your current weapon or survival needs.

Bring that same decision process into solo play or online co-op for up to four players. For a fresh run, download the free Mortuus demo on Steam and practice keeping weapon purchases, ammunition, and exploration within the same budget.
