**Portals** are the main mechanic of Modern Day. They can appear on any tile of the lawn and spawn various types of zombies. The placement and the zombies spawned are fixed and never change. There is never any indication on whether they are going to appear on a level, nor the zombies they will spawn.

If a portal appears on a tile occupied by a plant, that plant will be bounced to a vacant tile on the lawn. Instant-use plants and grid items can prevent a portal from appearing if placed where the portal is supposed to appear a little before they show up.

## Portal types

### Regular

This set of portals are the main ones most levels will use. They are also the portals that the Zombot Lawn-O-Tron spawns, for the most part.

### Veteran

This set of portals are commonly seen in the Expansion levels of Modern Day. Their codenames have "veteran\_" placed before the world codename.

### Endless 1

This set of portals are used in Vanilla's Highway to the Danger Room, but have been retired in *Reflourished'*s version of the Endless Zone. They are still usable on custom levels, however. Their codenames have "dangerroom\_" placed before the world codename.

### Endless 2

This set of portals are one of the sets used mainly in Highway to the Danger Room. In addition to having "dangerroom\_," they have "\_2" placed after the world codename.

### Endless 3

This set of portals is another set mainly used in Highway to the Danger Room. Unlike Endless 2, this one has "\_new" placed after the world codename.

### Modern Day - Day 48

Modern Day - Day 48 has its own set of portals containing different zombies. They have "\_modern41" placed after the world codename.

### Others

These are portals that don't necessarily fit in with the other sets. Some of them are used in only a few levels, such as step 5 of Future Crash! or Modern Day - Day 45.

### Custom portals

Custom portals have appeared in various levels in the game. As the name suggests, these are portals made specifically for the levels they appear in and nowhere else.
