Game modes

The game features four game modes. There is a secret bonus mode (puzzle mode), developers never said if completing the puzzle led to something.

Quest mode

The player has to complete 50 levels each with their own starting weapons and enemy layouts. As the player completes each quest they unlock weapons and perks.

Survival mode

The player tries to survive as long as they can as waves of enemies come after them. All perks and weapons that have been unlocked are available.

Rush mode

The player is equipped with the AK47 and has to survive as long as they can without any perks or bonuses.

Typ’o’Shooter

The player remains stationary in the middle of the map and is equipped with a shotgun. As the enemies make their way towards the player there is a word hovering over them. In order to shoot at the specific enemy the player needs to type out the word and press Enter. The longer the player survives the longer the words that appear over the enemies.

2014 re-release game modes

With the re-release of Crimsonland in 2014, new game modes were added.

Quest

The player has to complete 60 levels each with their own specific goals and weapons. While the main goal is to eliminate all the enemies, how that goal is accomplished is different. Many quests do not give the player the option of picking up alternate weapons. Also, perks can be disabled in the game's options screen to add even more difficulty. There are three levels of difficulty that the player can select from and if the player completes a quest with full health, a star will be marked on the quest in the quest selection screen. The quest mode is where the player unlocks most of the game's weapons and perks.

Survival

The player has to survive as long as they can while wave after wave of enemies appear at an increasing rate. All perks, weapons, and bonuses that have been unlocked are available in this game mode.

Rush

The player is equipped with the AK47 rifle as monsters and spiders make their way towards the player from the left and right sides of the screen respectively. This mode does not have perks or bonuses.

Nukefism

The player does not have a weapon in this game mode. Instead, the player needs to pick up bonuses to eliminate the enemies. This mode does not have perks or any point-based bonuses.

Weapon Picker

The player only has the bullets found in the weapon they picks up, there are no reloads. Weapons are randomly dropped throughout the map.

Blitz

Like survival mode but everything is increased. The monster count is increased to make the play time much shorter than in Survival mode. All perks, weapons, and bonuses that have been unlocked are available in this game mode.

Gembine

Gembine is a hidden game within Crimsonland. The game is very similar to the puzzle game 2048. The player is presented with a 4x4 grid and using the arrow keys, the goal is the combine the gems to create larger gems. With each combination of a gem, the player receives points. To play the game, the credits from the main menu have to be selected and typed as "gembine" with the keyboard, or if using a controller press on the right d-pad up up up left left left up. (For PlayStation controllers press "triangle" (three times) then "square" (three times) and finally "triangle" once.) (For an Xbox controller press "Y" (three times) then "X" (three times) and finally "Y" once.)
