Cats vs. Dinos is a gamemode in Plants vs. Zombies: Garden Warfare 2 that was introduced in the Trials of Gnomus DLC. This mode lets players play as the plants' and zombies' Infinite Robots (with their melee abilities changed to charged blaster shots) in the Gnomiverse, and there can only be up to eight players on each team. It can only be accessed by entering the Mystery Portal in the Town Hall, provided that it will be able to be played once the player enters the portal.
The goal of the mode is to have one team vanquish all the members of the other team. When an Infinite Robot is destroyed, it cannot be revived, and the player playing must wait until one team is wiped out. Also, Time Shards will spawn when an Infinite Robot is destroyed.
When a team destroys the other team, they will win the round. To ultimately win, one team must win three rounds, and sessions can be three to five rounds long, depending on the winning team. If a round lasts more than two minutes, the space-time continuum will start to collapse, and a blue force field will appear, covering the entire map and then start shrinking towards the middle of the map. If a player stays outside of the force field for too long, they will be vanquished.
Also, singularities will spawn randomly, with a warning appearing on screen whenever a singularly spawns.
Expeditions to the Gnomiverse XL don't go without their confrontations. It's time for newly upgraded Mechanical Cats to go head to head with Mechanical Dinosaurs in an all out battle of attrition.
- If the player completes a full session of Cats vs. Dinos as a Cat or a Dino, they will earn either the Alright Meow or the Open the Door Get on the Floor achievement, depending on what team they were on.
- If the player looks at the "Cool Stats" screen after a match, the "Revival Master" and "Heal Master" boasts will be darkened.
- This is because they are impossible to obtain, due to players unable to heal or revive other teammates.
