Natural Selection League
League Rules 2017
1. Mission Statement
The vision of the Natural Selection League (NSL) is to gather Natural Selection 2 players for international organized play. At its very core, we would simply like games to be played, in the hopes that this fosters tangible and meaningful relationships among its participants. We realize that its participants span the range of commitment, skill, and time zones and will do everything possible to cater to everyone’s needs and create the most enjoyable experience.
(a) Before teams play their first matches, ALL players must read and completely understand the rules.
(b) The guidelines outlined in this document are to be used as the league standard, overriding all previous rulesets. Contests outside of normal seasonal play may have their own ruleset.
(c) Although this document strives to be comprehensive, not every situation may be specifically addressed. The referee on hand during matches or an admin may be called upon to interpret the rules as they see fit.
(d) If at any point during the season, a situation arises where a rule or format of play revision is needed, the NSL staff, represented by the League Admin, reserves the right to do so. There will be a strong attempt to keep this to a minimum as to not interfere with the current season’s play.
(e) If a rule amendment that greatly affects gameplay is deemed necessary, it will be posted on the front page of the NSL website as a news post. Minor revisions will be posted in the NSL forums.
(f) If a team attempts to manipulate or exploit an NSL rule in any way other than for its intended use, NSL staff reserves the right to make a final decision and interpretation on the rule in question for the given match and/or dispute.
(g) An admin’s interpretation of the rules and decision is final.
(h) No revised rule will have retroactive power.
3. Code of Conduct
(a) All participants of the NSL are required to uphold and observe a universal level of fairness and sportsmanship. Any unsportsmanlike action which can include, but is not limited to racism, profanity, rude or vulgar acts, abusive remarks, and disrespect of an official are not tolerated.
(b) Teams and/or players who engage in unsportsmanlike conduct are subject to suspension, match forfeits, or any other punishment that the NSL deems necessary. Multiple and persistent infractions will be faced with stiffer consequences.
(c) Any accusations of unsportsmanlike conduct or cheating should be submitted to the League or Head Admin and will be investigated by the NSL staff. Any deviation will result in consequences..
(a) The NSL is for teams that span a wide range of commitment to playing, but first and foremost the NSL prioritises active teams.
(b) Signing up for a season or contest means declaring your intention of playing a weekly match during the course of the season and every match during a contest.
(c) By the time of the deadline for signing up for any season, ALL teams must have a minimum of six (6) registered users.
(d) After the season begins, all division teams must maintain a roster of at least five (5) registered users.
(e) There is no maximum to the numbers of players rostered onto one team.
(f) Teams may add and remove as many players to and from their roster throughout the course of a season until rosters are locked.
(g) Rosters will be locked and changes are no longer permitted, one (1) week before the conclusion of the regular season for each respective division.
(f) Teams who do not complete the season or contest, may be removed by an admin and all future and previous matches, for that season or contest, will be given a forfeit score with the appropriate amount of points awarded to their opponent.
(g) If a team disbands, it must notify the League or Head Admin.
(h) Team names containing, but not limited to, any of the following will not be tolerated: emotes, profanity, racism, sexism, or general vulgarity. Teams found with offensive names may be contacted by an admin and asked to change their name to something more appropriate.
(a) Each player must be a registered user with a valid SteamID on the NSL website atwww.ensl.org
(b) A player may only use one (1) account and may not register multiple accounts on the NSL website.
(c) Players who are having trouble accessing their NSL account should contact an admin for assistance before creating a new account.
(d) A player may only be a rostered on one (1) active team per season or contest, regardless of division.
(e) After the season begins, a player who joins or switches teams will be ineligible to play for that team as a member for seven (7) days. That player is eligible to play as a substitute.
(f) Names containing, but not limited to, any of the following will not be tolerated: emotes, profanity, racism, sexism, or general vulgarity. Players found with offensive names may be contacted by an admin and asked to change their name to something more appropriate.
(g) Players from teams that have disbanded in higher divisions may be ineligible to play in lower division teams, if it is believed that the player may disrupt play (i.e. They’re too good for that division). A final determination will be made by an admin.
(h) Players who have participated in teams, which did not disband and concluded a season, are not eligible to join teams still participating in a season.
The intention of substitute players is to allow teams, that cannot field 6 players, the ability to play their matches. It is NOT to be used to bolster the skill of a team’s roster.
(a) Substitute players must follow the player guidelines in Section 5.
(b) Teams in Division 1 may substitute up to one (1) player, not from their roster for use during a match. Teams in any other division may substitute up to two (2) players.
(c) The player(s) must be of equivalent or lower skill than the rest of the replacement's team. A quick parameter to determine a substitute’s eligibility may be the division of the team that player belongs, but may not be sufficient. A referee or admin can determine a player’s suitability.

(e) Substitutes can not be denied in an attempt to force a forfeit.
(f) Substitutes may only be denied on the basis of perceived higher skill compared to the average skill of rest of the team.

(i) Players effectively playing in two teams
(ii) Teams boosting their line-up by regular use of substitutes
(a) The maps in the current season’s regular rotation will be:
8. Match Procedures
(a) What is a Match?
(i) A match during the regular season will consist of two (2) maps.
(ii) Teams will play one (1) round of marine and alien side on each map. Matches will be listed as “Team A vs Team B”. Team A will start as marines on both maps during normal seasonal play.
(iii) One (1) point will be awarded for each round won. A maximum of four (4) may be awarded during each regular season match.
(iv) A match during the playoff portion of the season will follow a best of five (5) or seven (7) format. To decide on sides, maps and servers, the following steps ((v)-(vii)) are performed in sequence:
(v) At the beginning of the match the higher seeded team is determined by:
* the overall collection of points during regular season
* if tied: the collection of points against the other team during the regular season
* if tied: the number of won matches during the regular season
* if tied: by coin flip.
(vi) The higher seeded team chooses one of the following, the non-chosen goes to the lower seeded team:
* To play Aliens or Marines in the first round (called "side-picker")
* To choose the map for the first round (called "map-picker")
The side-picker decides on sides for the first round.
(vii) The lower seeded team reduces the map-pool by one maps. Then, the higher seeded team reduces the map-pool by one map, again. In a best of five (5) format this step is performed 3 times, leaving 3 maps. In a best of seven (7), this process is repeated 2 times, leaving 4 maps
(viii) The map-picker chooses the first map to be played and if necessary the third map. The side-picker chooses the second map to be played and if necessary the fourth map. All maps must be chosen from the above reduced map-pool. A map can not be choosen twice.
(ix) Teams switch sides (Marines/Aliens) after each round.
(x) The first team to win three (3) rounds in a best of five (5) format or four (4) rounds in a best of seven (7) format, wins the match.
(b) Scheduling a Match
(i) There are no default times for matches.
