Zombies are the titular and primary antagonistic force of Project Lazarus.

Zombies relentlessly pursue living players and will attempt to attack with their arms when within striking distance. They spawn outside of the playable area of the map and break apart barriers in order to reach the players.

As the rounds increase, the incoming zombie horde becomes increasingly difficult to defeat. While a single zombie is slow and lumbering, their overwhelming numbers and sheer persistence will prove deadly.

Appearance

As deceased humans, zombies have a humanoid form similar to that of players. Their legs and torso have a brown color while their arms and head are a greyish shade of green. Their distinctive eyes glow with a bright yellow color.

Zombies also emit a faint green light to their surroundings. This is most noticeable when many zombies are grouped together. This can give away the location of zombies and the size of their group from around a corner, even if the player cannot see the zombies themselves.

Behavior

Zombies spawn outside of the playable area of the map and attempt to enter through windows and doors. If their entrance is boarded up, zombies will slowly tear down the barricade before climbing through.

Once within the playable area, zombies will target players who are still alive, prioritizing the closest, and take the shortest path towards them. Zombies will always know where the players are, even if they are across the map.

Zombies will ignore players who are downed and will instead turn their attention toward active players.

Attacking

If a zombie gets within range of the player, it will attempt to swipe at them. Each attack is randomly launched at slightly different speeds, taking from 0.5 to 1.0 seconds to connect.

If the player is still within striking distance after the short delay, they will suffer 45 damage. This means that players will be downed in three hits, or five with Juggernog.

The zombie is slowed by 50% while performing its attack, which gives the player a better chance to move out of the way.

After fully completing its swing, the zombie waits for 1.25 seconds before being able to swing again.

Zombies attack and damage barricades in a similar manner when entering the map, taking down one plank with each swing.

Sounds

Zombies occasionally make groaning sounds as they walk. They also make aggressive grunts when attacking the player.

Zombies give out a final groan when they are killed.

Scaling

As the rounds progress, the zombies that the player face becomes more and more powerful. Zombies gain more health, faster movement speeds, and grow in numbers.

Health

Zombies spawn with increasing amounts of health depending on the round number.

Zombies start at 150 health points in the first round. For the first nine rounds, the health pools of zombies are increased by a flat 100 hit points each round.

On round ten and onwards, their health points increase by 10% instead. While 10% may not seem like a massive difference at first, the growth is exponential and zombies start to increase in health at an accelerating rate.

The starting health of each zombie is represented by the following formula:

$\text{Health} = \left\{ \begin{array}{ll} 50 + 100 \times \text{Round} & \mbox{if } \text{Round} < 10 \\ 950 \times 1.1^{\text{Round} - 9} & \mbox{if } \text{Round} \geq 10 \end{array} \right.$

Health by Round

The following table shows the amount of health each zombie has depending on the round.

Round	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	30	40	50	75	100
Health	150	250	350	450	550	650	750	850	950	1045	1150	1264	1391	1530	1683	1851	2036	2240	2464	2710	7030	18235	47296	512437	5552109

Movement Speed

As the rounds progress, the zombies also start to move quicker.

In the first round, zombies have a movement speed of 6.5. This number grows linearly by 0.5 for each round, up to a maximum of 11 on round 10. For reference, the player walks with 14 movement speed with a full mobility weapon, such as a handgun.

Some zombies moves slightly faster or slower from the base speed. There is a random variance of ±1.5 for each individual zombies to provide more variance between zombies.

The base zombie movement speed for each round is represented by the following formula:

${\rm Movement\ speed} = \left\{ \begin{array}{ll} 6 + 0.5 \times \text{Round} & \mbox{if } \text{Round} < 10 \\ 11 & \mbox{if } \text{Round} \geq 10 \end{array} \right.$

Movement Speed by Round

The following table shows the base movement speed of zombies depending on the round.

Round	1	2	3	4	5	6	7	8	9	10+
Speed	6.5	7.0	7.5	8.0	8.5	9.0	9.5	10.0	10.5	11.0

Amount

For more information, see Rounds.

The number of zombies that make up each round increases depending on the round. This number also varies depending on the total number of players at the start of the round.

The growth is quadratic, meaning that number of zombies in each round will grow at an increasing rate.

A solo player in a server has to kill 6 zombies in Round 1, but hundreds of zombies per round in later rounds.

The rate at which zombies are spawned into the map also increased by round. In early rounds, there is a long delay between zombies appearing on the map. However, zombies will quickly fill the map in later rounds.

To prevent the server from lagging, the number of zombies that are alive on the map at the same time is capped at 24. Additional zombies will wait until the current number of zombies on the map is dropped below this cap before spawning in.
