This article gives an overview over the game modes, gametypes and level types that are available in SRB2. The three concepts are closely related, as they all define ways of playing the game. However, there are subtle differences:

A gametype defines the fundamental rules for how the game is played. For example, in the Match gametype, players score points by shooting rings at each other, and the objective is to score the most points, while in the Single Player gametype, the player must overcome obstacles to reach a goal. A level type defines the gameplay rules for a specific level. There are two groups of level types: The first group specifies which gametypes the level supports. The second group consists of supplementary level types that add further gameplay rules or modify existing ones specifically for the level. An example of a supplementary gametype is 2D mode, which adds the gameplay rule that the player's controls are restricted to two dimensions.

A game mode is any option that the player chooses in the main menu to start a game. It can also define gameplay rules, but primarily it specifies the context and presentation of the game. For example, two-player splitscreen games and netgames both rely on the same gametypes with the same gameplay rules, but one is played by two people on the same computer, while the other is played over the internet.

Game modes

SRB2's game modes are divided into two fundamental categories: single player and multiplayer, both of which have their own entry in the main menu. In each sub-menu, there are several subordinate game modes. Choosing one of these will start a new game.

Single Player

Main article: Single Player
  • The campaign is the standard way in which players experience the game. They choose the "Start Game" menu entry, pick a save slot and play the Single Player maps sequentially. The save slots allow players to restart at the first level of the current zone. Once the last level has been completed, the credits roll and the save slot turns into a level select.
    • Ultimate mode is an easter egg in which the player must beat the entire campaign in one run without getting hit once. All power-ups except invincibility and speed shoes are removed and the player has only one life. It is unlocked by typing ULTIMATE on the title screen, which will turn the "Play without saving" option into an "Ultimate mode" option.
  • Record Attack is a game mode in which players replay the maps from the campaign and attempt to establish records for fastest time, highest score and most collected rings. Replays are recorded in this mode that the player can play back and watch, or compete against. Levels are unlocked for this mode once they have been visited in the regular campaign or, in the case of secret maps, unlocked.
  • NiGHTS Mode is a game mode in which players replay the NiGHTS maps (which include the Special Stages and Spring Hill Zone) and attempt to achieve an A rank or establish records for fastest time and highest score. Each map becomes available in NiGHTS Mode once it has been visited in the regular campaign or, in the case of secret maps, unlocked.

Multiplayer

Main article: Multiplayer
  • Two-player games, also called splitscreen games, are played by two people on the same computer. The screen is split vertically to provide a separate display for each player.
  • Netgames are played over the internet. One player hosts a server on their computer and other people join the game by connecting to the server from their own computers. The server can either be advertised publicly on the SRB2 Master Server or, if the netgame is intended to be private, the other players can join by specifying the IP address of the host.

Gametypes

Since the Single Player game mode only features one gametype (also called Single Player), most of SRB2's gametypes are multiplayer gametypes.

  • Single Player and Coop are functionally identical and the game internally considers them to be the same gametype. The difference is that Single Player is played in the Single Player game mode, while Coop (which is short for Cooperative mode) allows players to play the Single Player maps together in multiplayer.
  • Competition is similar to Sonic 2's two-player mode. Players run through the Single Player stages, trying to collect as many items and earn as many points as possible. When one player has completed the stage, the other players have 60 seconds to complete the stage or they will die and the round will end. At the end of the round, players will be ranked in several categories, such as score, time, and collected rings.
  • Race is also played on the Single Player stages. The objective is to reach the goal as fast as possible. The player with the fastest time wins.
  • Match is a gametype akin to traditional deathmatch first-person shooters, played on its own roster of maps. Players toss rings at each other to score points. Hitting a player will make them lose all their items and rewards the scorer with 50 points (or 100 if the opponent is hit without any items and dies). 50 points penalty are subtracted when a player dies. There are six special weapon rings that exhibit a different behavior from regular rings, but the players need to collect weapon tiles and ammunition to use them. Additionally, the seven Chaos Emeralds spawn in random locations in the map, which allow a player to switch to their Super form if collected.
  • Team Match works exactly like Match, but the players are divided into a blue and red team. The team with the most cumulative points wins.
  • Tag and Hide & Seek are two closely related gametypes that are typically played on Match maps. In both cases, one player is selected to be "it" and then has the objective to find and shoot the other players. The score of the hiding players increases with time until they are shot, while the player who is "it" receives points for every found opponent. In Tag mode, all players can move freely, and shot players become "it" as well, while in Hide & Seek, movement is disabled for the hiding players after a set amount of time, and shot players do not become "it".
  • Capture the Flag is similar to Team Match, but each team controls a base containing a flag. The objective of each team is to steal the opposing team's flag and bring it to their own base, while still being in possession of their own flag. If this is achieved, the team scores a point. The game ends when one team has scored five points. Capture the Flag is played on a roster of maps designed specifically for the gametype.

Level types

The level types for a map are defined with the TypeOfLevel parameter in the level header. There are two groups of level types: gametype-specifying and supplementary.

Gametype-specifying level types

These level types specify which gametypes a level supports. Therefore, they generally correspond to the existing gametypes, except for gametypes that always share the same maps, which are merged into one level type. At least one gametype-specifying level type must be given to each level, otherwise it would not be playable. A level can support multiple gametypes, but it can only be played in one gametype at a time.

The following gametype-specifying level types exist: Single Player, Coop, Competition, Race, Match (includes Team Match), Tag (includes Hide & Seek) and Capture the Flag.

Supplementary level types

These level types modify certain gameplay aspects regardless of the gametype that the map is played in. While they technically take effect in any gametype, it generally only makes sense to combine them with certain gametypes.

  • 2D mode restricts the player's movement to two dimensions. It is normally used in conjunction with Single Player, although it is theoretically possible to use it with any gametype.
  • Mario mode emulates Super Mario-like gameplay in SRB2. On its own, it mainly exchanges some sounds to fit the Mario theme and enables the Fire Flower item to be used. It is used in conjunction with special graphics and level elements to create Mario-themed levels.
  • NiGHTS emulates the SEGA game NiGHTS Into Dreams in SRB2. The player flies along a curved 2D track as Super Sonic, flying through hoops and collecting items to destroy an Ideya Capture. SRB2 uses this mode for its Special Stages. NiGHTS should be used in conjunction with either Single Player or Race.
  • ERZ3 mode was used for Egg Rock Zone Act 3 in v2.0 to make Brak Eggman appear larger. In this mode, all Objects besides the old Brak Eggman are scaled down to 50% of their normal size.
  • Christmas NiGHTS exchanges a few NiGHTS-related graphics and sounds to be Christmas-themed. It is unused by SRB2 itself. Note that NiGHTS maps that have this level type still need to have the NiGHTS level type as well.
  • Custom is an option that does nothing by itself but can be used by Lua scripts to create a custom level type. The simplest way to do this is by using the MapLoad hook to check if the current map supports the Custom level type and then applying the desired changes.

Other level types

These level types are not technically considered as such by the game, in the sense that they are not specified via the TypeOfLevel parameter, but they nonetheless serve the same purpose. They are specified by other means, such as putting the level in a special map slot or placing a special Thing on the map.

  • Special Stages are levels where the player tries to obtain a Chaos Emerald. They are stored in specially designated map slots and are automatically warped to when the player finishes a level after having collected a Special Stage Token. SRB2 supports two types of Special Stages: NiGHTS stages like the ones that are used in SRB2 itself, and levels where the player must collect a certain number of rings in a certain time, like the Special Stages in old versions of SRB2.
  • Emerald Hunt is a level type where the player's objective is not to get to the goal, but to collect three emeralds that are hidden in the map, similar to Knuckles's stages in Sonic Adventure. Emerald Hunt maps are normal Single Player levels, but instead of an exit sector, emerald spawn points are placed on the map. If such spawn points are present in a map, the game will automatically end the level once the player has obtained three emeralds.
  • Circuit is an alternative type of Race level in which the maps have a circular layout, and in which the players must complete a certain number of laps through the finish line (marked by the Circuit Finish Line sector type) to finish the stage.

Outdated gametypes and level types

These gametypes and level types were once featured in SRB2, but have been removed for various reasons and are no longer in the game.

  • Chaos was a gametype that was introduced in SRB2 2k3 and remained in the game until Final Demo 1.08. In this gametype, random enemies would spawn from designated spawn points and players would compete to kill these enemies for a high score. Killing multiple enemies in one move would increase the score rapidly, while dying halved it. Chaos was played both on Match maps and on maps designed specifically for the gametype, which were similar to Match maps but generally smaller and simpler. The gametype was poorly received and was eventually disabled in Final Demo 1.09.
  • Ice Hockey was a level type that only appeared once in Final Demo 1.08 and was only used for a single stage Ice Hockey Zone. It was similar to CTF, the objective being to push a snowman onto the goal of the opposing team. Due to a bug, the map was not playable and the mode was subsequently removed.
  • Golf was a level type that also appeared in Final Demo 1.08, to be played on Single Player levels. Golf levels played similarly to normal Single Player levels, but in a golf-like fashion: The player was unable to do anything except charge spindashes to move across the level. Each spindash would be counted as a "putt", the total of which would be compared against the map's par requirement to gain bonus points at the end of the level. No Golf maps were included in SRB2 officially, and the level type was scarcely used at all, which led to it being removed in the next release.
  • Adventure mode was a level type during the Final Demo era that emulates some gameplay elements of Sonic Adventure, such as analog control, the homing attack and the light dash. It was used for the unlockable Adventure Example Zone. While analog control is still available as a control scheme and the homing attack is usable as an ability for custom characters, the level type itself was removed in v2.0 due to poor reception and limited usage.
