Four priorities before you queue
Slide. Parry. Grapple. Stay high.
I · Slide
Master the 1-second slide prerequisite
The Circle Slash is unlocked by sliding for one continuous second. Without it, your melee is half-damage and fully parryable.
Slide mechanic →II · Parry
Pre-cast parries by your one-way ping
Phantom parries happen when your local parry input registers but the server receives it too late. Pre-cast by Ping ÷ 2 to compensate.
Parry mechanic →III · Grapple
Convert lateral velocity into centripetal acceleration
Tap grapple mid-air for a flick swing. Chain grapple → slide for frictionless momentum. Aim at angled anchor points, not flat walls.
Grapple mechanic →IV · Maps
Take the high ground in 75-player FFA
The ground floor is the deadliest Z-axis. Wallrun + grapple to stay above the Rocket and Shotgun spam.
Skyline Arena →Top of the meta
Four weapons every serious player keeps in rotation.
Revolver
S-Tier precision hitscan / high-velocity projectile. Documented as the most fun and highly preferred weapon for competitive 1v1 stocks duels. Offers unparalleled point-and-click precision that lets highly skilled users bypass the chaotic Ao
Phoenix
A-Tier high-yield linear projectile / splash ordinance. Heavily criticised as a spam weapon, yet mechanically dominant because its projectiles can ONLY be parried if fired directly at the defending player's centre of mass. Aiming slightly o
Shotgun
B-Tier burst CQC / spread projectile vector. Highly effective in chaotic 75-player FFA environments. The wide-spread damage vector punishes opponents who fail to maintain maximum velocity. Its close-proximity reliance makes the user vulnera
Rocket Launcher
C-Tier AoE / heavy slow ordinance. The Rocket is described as 'too easy to land' due to its massive AoE radius, paradoxically pushing it to the bottom of the competitive tier list. Easily readable, possesses massive travel times, and severe
Common asks on the server
Common questions. Full list in the FAQ.
What is REDLINER?
REDLINER is a high-skill-ceiling movement shooter on Roblox by Qitadel. It combines parry-based swordplay, grappling mechanics, and dynamic gunplay in a custom physics environment with no speed limit. It supports 75-player Free-For-All lobbies and 1v1 stock-based duels.
How do I parry?
Press F when an incoming attack is within your parry cone. The base window is 250ms (15 frames at 60Hz). For Phoenix projectiles, the cone narrows to 4.5° - only head-on shots are parryable.
What is the Circle Slash?
Circle Slash is a hidden melee variation unlocked by sliding for one continuous second. It applies a 1.25× damage multiplier and swings along an off-axis vector that bypasses most parry windows.
What is Yen?
Yen is the singular hard currency of REDLINER. Earned via eliminations, duel stock victories, and survival time. Spent exclusively on cosmetics - weapon skins, trails, and visual effects.
Is Roblox Plus worth it for REDLINER?
Roblox Plus members earn +50% Yen on every source. The +50% multiplier reduces grind time by approximately 33%. Use the Max Level & Yen Farming Optimizer to model your exact break-even point.
What is 'speed begone'?
The 'speed begone' bug is REDLINER's most frustrating physics anomaly. During a chained momentum vector (typically a bunny-hop into a slide), the physics engine occasionally zeroes out your velocity completely. The 06/13/2026 patch reduced reproduction by 17% but did not eliminate the bug.
