Nation Red: How Perks, Power-Ups, and Four Modes Change the Fight

A Manual-Based Tour of Nation Red's Combat Systems

Nation Red is an arena shooter built around a deliberate split between movement and targeting. The WASD or arrow keys walk the player around the battlefield, while the mouse cursor decides where every attack lands, so the first skill the manual stresses is doing both at once. Around that core loop sit two layered systems: experience points that unlock perks, and short-lived power-ups that can be stretched by the perks you choose. The modes then decide which of those systems you actually get to use.

Four Ways to Move, Aim, and Strike

Positioning begins with the WASD keys or the arrow keys, while aiming follows the mouse cursor: attacks always fire toward wherever that cursor sits, so movement and targeting stay separate tasks. The E key jumps, giving a quick way to leave danger. Clicking the right mouse button performs a physical attack such as a round kick, which disables several enemies for a few seconds; following it with a left-click finish lets a kick soften a cluster before a weapon strike. Holding a melee weapon and holding the left mouse button for a few seconds before releasing performs a 360-degree attack.

The Q key swaps primary and secondary weapons, and the F key locks or unlocks each slot separately so a locked slot refuses new pickups. The R key reloads at any time. Page Up, Page Down, the middle mouse button, or pushing the cursor to the top or bottom screen edge sets camera height; a high overhead view helps against large enemy groups.

Perks, XP, and the Bonus You Never Took

Experience points accumulate per kill, and each new experience level makes another perk available. Pressing the Space Bar pauses the game so you can pick one from the list; canceling the choice instead banks an unselected perk bonus that is added to your final score. Difficulty, set with the TAB slider and confirmed by pressing TAB again, changes how fast this happens: lower settings reduce the experience points earned per kill, while higher settings increase them. That difficulty can only be adjusted during the first minute of any one game.

Perk Modes decide how those level-up selections arrive. Random is the default, presenting a random list each time you level. Strategic lets you select the exact perk you want, but caps you at ten perks per game. Auto Perk Mode builds a favorite list saved between games and randomly but intelligently assigns new perks from it when you level; the more perks you include, the closer it behaves to Random. Outside Survival, where ranking comes from total survival time, your score sums experience points, accuracy bonus, life bonus, and the unpicked perk bonus.

Power-Ups and Perks That Feed Each Other

Power-ups are collected by walking over them, and each lasts only a short time. The shield protects you from damage briefly, the grenade cache supplies three fragmentation grenades, and the dynamite item is a 5-pound time-delayed bomb that kills or damages most enemies on screen. The ghost power-up spawns a temporary clone that attacks and kills enemies on its own until the effect expires. Perks can stretch these pickups further: Power-Up Extender lengthens the duration of any power-up, while Intensity makes any projectile weapon you pick up fire at a faster rate.

Explosives show a clear division of harm: every explosion you cause, whether from grenades or dynamite, damages only enemies, while explosions created by enemies are the only ones that can hurt you. Most explosions also spray shard projectiles outward for extra damage. Grenades detonate within a 5-meter range that kills or severely damages nearby enemies, and the Remote Detonator perk changes the right-click trigger so the grenade goes off at the cursor position instead. Projectile weapons differ in rate and reload, from the M4A1 Carbine's 2.3-second reload and 1.15 weight multiplier to the Minigun's 18 rounds per second and 1.45 weight multiplier.

Survival, Free Play, and Barricade: Three Modes, Three Pressures

Survival Mode strips the loadout down to a single starting weapon. There are no power-ups to collect and no perks to earn, so every kill has to come from what you already carry. Enemies grow harder as time passes, and the mode has no finish line; the aim is simply to record the longest possible survival time. Free Play Mode uses the same continuous pressure but restores the full system: power-ups can be picked up, experience accumulates, and level-ups open perk selections. Its stated goal is to gain the maximum possible experience points, which means pushing deep into a run rather than banking on a short burst.

Barricade Mode turns the arena into a defense line. Zombies arrive in waves, and each successive wave adds more hostiles. Barricades, sentry guns, and soldiers are placed to stop the attackers from reaching the base entrance or overrunning your position. Sentry guns can be manually reloaded, and standing beside one upgrades it into a weapon station. Perk Modes apply to Free Play and Mission play once unlocked by completing the full mission range. Multiplayer offers local co-op and online co-op requiring a Steam account, with options such as friendly fire and shared experience set before hosting.

Missions and the Progression Gate

Mission Mode presents a series of missions, each requiring different tactics; completing one unlocks the next, and later missions are described as nearly impossible or dependent on a particular combination of perks and power-ups. You can replay any unlocked mission to chase a higher score, and replaying reverts you to the total score you had before that attempt. This is also the gate for the perk systems: Perk Modes unlock only after the entire range of missions is completed.

Source-Backed Starting Advice

Play the documented mechanics against each other. Right-click to disable a cluster with a physical attack, then left-click to finish the stunned enemies. Save grenades for moments when you are cornered, since player explosions cannot hurt you and every hit lands on enemies. Decide on difficulty in the first minute, because the slider locks afterward and because higher difficulty raises the experience points each kill provides. When a random perk list appears, weigh the immediate upgrade against the unselected perk bonus that feeds your final score.

Controls, Platforms, and Package Notes

The manual documents an Xbox 360 Controller and generic gamepads, with calibration required in the gamepad options for generic pads; the mouse only works when the use-gamepad option is turned off. The official store page lists DiezelPower as developer and publisher and Windows, macOS, and Linux as platforms, so the manual's input notes should not be assumed to translate unchanged to every platform without checking that platform's options.
