Tips of Team Sprint

This achievement condition is to get on ship with 4 players within 5 minutes.

However, in reality, your team needs to board ship within approximately 4 minutes and 45 secounds.

Because it seems that the flight time of ship is also included in the count.

By the way, this achivement can be obtained even if “Level time” displayed on Mission Complete screen is 5 minutes or more.

Here are the points to progress the mission in short time.

1. Have 4 players pass through the first gate at approximately the same time. Otherwise, the gate will remain closed for several minutes for players far away.
2. Get on the train right away. If 3 players board the train, after a few seconds the 4th player will be teleported inside the train.
3. Ask the corpse in the restroom which lab has the vaccine.
4. At least 1 player should get the vaccine. Then you can call ship. Not every players need to get the vaccine.
5. Ignore bosses
6. Ignore loots
7. Hurry up and get on the ship
8. Done

Tips of Zero Casualties

Many other older guides say this achievement doesn’t work.

But that’s not true.

It was fixed in version 2.0 (Sep 20, 2022) and now works fine.

Here are some tips for getting this achievement:

• Must be a Power Out map
• Must be a 4-player team.
• No shock weapons. To avoid breaking crates. The lower the player’s level, the less they have that weapon.
• Line up the crates after you hit the first switch.
• Attack the central turrets from a short distance away from the crates to avoid being damaged by the blast.
• Help members of the team. To avoid leaving the group in the middle of the game.

Tips of Zombies Go Boom

This is hard.

You need a bunch of zombies.

To do so, play vaccine map in Single Player mode.

The first area is full of zombies.

Kill zombies there with “Aerial Bombardment”.

Quite as sonn as the Aerial Bombardment ends.

Repeat these.

This way you will get this achievement relatively quickly.

Tips of Map Master

I will tell you about the following achievements in summary.

• Map Master – Pods
• Map Master – Survivors
• Map Master – Vaccine
• Map Master – VIP
• Map Master – Last Stand
• Map Master – Onslaught
• Map Master – Power Out

Of all the achievements, these are probably the hardest to get.

You have to complete 1000 missions on each map.

Some complain that it is one digit higher.

For “Pods” map, you may be able to complet one mission in under a minute.

But for other maps you can’t do that.

Use “Last Man Standing” event to accomplish that.

Here’s how to do it:

1. Take off all armor
2. Only carry guns with no movement penlties
3. Play Last Man Standing
4. Get killed by zombies right after the mission starts

This way you can complete the mission in a minute or two.

And repeat this over and over.
