Red Eclipse features a Capture the Flag game mode, which is usually present in a first person shooter game. The mode is as it sounds - the players group into teams, with one flag position for each team, while the objective is to steal enemy teams' flags and bring them to the own flag base. The action of bringing other team's flag to your base is referred to as 'capturing' the flag. Capturing is only possible if own flag is in its place and not stolen by an enemy team player, otherwise in order to capture, first the own flag has to be brought to the base.
The impulse moves feature of the game brings an additional dimension to this mode, as the player will have many strategies to choose from in order to reach the objective. Players may choose to take the flag and forcefully go through enemy teams' players to reach their own base, or choose other, non-obvious ways to reach their base without being spotted by the enemy, using parkour moves to travel via less-known paths.
Generally, the objective is obvious, the players reach enemy base, steal the flag and try to take it to their own base while not being killed. The amount of teamwork needed for this mode varies from map to map. Usually, little teamwork is needed if the team has one very good player that will unbalance the game score. Also, different mutators might require coming up with a unique strategy for Capture the Flag games.
The situation where both teams hold the enemy flag near their own base will be referred to as 'standoff'. That poses a dilemma for a player that has just brought an enemy flag to his own base and found out that his team's flag is missing - either to assist his team in returning the flag and risk losing the enemy flag, or hide and wait for his team to retrieve the flag and score upon retrieval. When a standoff is broken on a large map, meaning a team player got hold of his team's flag near the enemy base, it might be faster to throw the flag into lava/abyss and wait for it to reset rather than go all the way and bring the flag back.
This is an unofficial name for an observed tactic - when one player steals the enemy flag, another player stays near the enemy flag point and waits for the flag to reset upon capture, just to steal again. Very frustrating when executed on a less experienced team of players. Having a good defense might help avoid this situation.
Protecting the team's flag is important, for obvious reasons. There are multiple ways of doing that, among them are mining the flag, patrolling the general flag area, and kamikaze - suicide while holding a grenade. Kamikaze'ing is very effective when the attacking force is only one player, and very easy to execute: standing with a grenade near the flag and committing suicide just when the attacking player grabs it. One must be careful not to explode too early, and not die before the attacker grabs the flag. Also, if the attacking force is more than one player, kamikaze is not advised, since the remaining attackers will be able to steal the unprotected flag before the kamikaze re-spawns.
Buffsthe buff. The buff is on even if the flag is not on the home base, meaning that a player can carry the flag and buff his teammates. Apart from making the job easier for the defending players, the buff opens up a possibility for another tactical maneuver - bringing the flag closer to the front line, possibly even to the enemy base. While obviously being very risky, bringing the flag to the enemy brings the buffed attacking players as well. Risky maneuvers are usually advised against, but might come in handy when losing by one point at the end of the round. The risk is lowered if there is a place to safely drop the flag near the enemy base, meaning the team can rush in buffed and then drop the flag to reset it.
Instagibmutator leaves the players with 1HP, meaning one hit/shot/slice will be the death of the player. On some maps players would find secret or less known ways of bringing the flag home, so they don't get instantly killed, since a player cannot sacrifice some of the HP in order to steal the enemy flag, like they can in vanilla Capture the Flag.
Survivorsuicide when the player is the last one of his team, because then all the teammates are brought back into the game. One point is gained each time a capture has been made, and players and flags reset after that.
