The FP-500 Combat Walker, played

Landing

• It does not walk off the Phantom. The script drops it from 40 high onto a fixed point, a 1 s fall, and the slam shakes the camera of every hero within 8. Your camera stays locked until it lands; the Overdrive panel appears 3 s later.
• There is no sprint bar for the walker; the script skips it. Turbo, from Chassis 1, is its only burst of speed.
• One walker per game, on the Warrant Officer track only: the Enlisted and Commissioned buttons are greyed out for it. With the Classical modifier it is off the roster.

Reloading

• The drum holds 200 rounds and a change takes 20 s. The reload code takes 2 s off per Main Weaponry level, then multiplies by 0.8 at Chassis 4, by 0.7 with Quick Thinking, by 0.85 under an Instructor aura, and by 0.95 to 0.8 under a Leadership aura. 20 s is 12 with Main Weaponry 4, 9.6 with Chassis 4 on top, 6.7 with Quick Thinking on top of that.
• Every change spends 2 magazines and discards what was left in the drum. The walker cannot hold a Magazine Extender.
• Chassis 3 grants Jam Immunity; until then the miniguns can jam.

When it dies

• A dead walker is a wreck, not a body: it is brought back by repairing the wreck, not by a medic. An engineer's Reconstruct does it. So does the Wmk-72 RTo 3, a bot the APC builds as an item: used within 12 of the wreck, it walks over, revives it and blows itself up. With no dead vehicle within 12 it drops back on the ground as an item instead of being spent. With the Auto-revive modifier, or for a player with no XP on record, a drop pod delivers that bot on its own 2 s after the death.
• It comes back at 400 life and 50 energy, its camo and its unlocks re-applied, and with jam immunity whatever its Chassis level.

Overdrive, F1 and F2

• The class panel that appears after landing: F1 one level up, F2 one down, or click its arrows. The keys only answer while the class mini panel is shown.
• Levels 0 to 5, the number on the panel. Each level is move speed paid with your own life; the panel's description on this class page lists the numbers per level. The community's page warns it can kill the walker.
• The level is never reset. It is written only by the F1 and F2 handlers, and the revive fix puts back jam immunity, the camo and the unlocks, not an Overdrive behaviour. After a revive the panel still reads the level you died at while nothing sits on the hull, until one press of F1 or F2 puts a behaviour back.

Engine Overheat

• Chassis 4 unlocks Engine Overheat. The community's page notes there is no off switch. It ends at 30 seconds, when the energy runs out, or on a Reload, which costs 2 magazines and whatever was left in the drum.
• Power Cell (190 energy over 20 s) is what refills the tank afterwards.

Two ways to fire

• Rockets must target a unit. Your first point in it also sets Rockets (free aim) to level 1, and the script never raises that level; Switch Rockets Mode flips between the two.
• There is no free-aim EMI: the only free-aim ability in the class's list is the plain Rockets one.
• Any rocket you fire (Rockets, free aim, EMI, Cluster Rockets) makes the AI-controlled biological units within 5 of the target point scatter, and paints a target marker on the ground for 1.5 s. Only computer-owned units are moved. Your minis and every hero stay where they are, and both rocket tooltips say the blast hits allies.

The flare gun counter

• The counter runs in any mode above Recruit until Flare Gun is unlocked, as an objective only you see, under the URUnlock ranks trigger group.
• The trigger only counts kills whose damage effect is one of RocketDamage1 to RocketDamage4; which of the rocket abilities fire those effects is not in the extracted data.
• A rocket that kills an ally's or a neutral's unit raises it by 50, 250 with Outbreak, but only when that unit is biological or one of the vehicles or sentry guns. Every other kill, your own units and your minis included, lowers it by 1.
• The counter starts at 100, 500 with Outbreak. At 0 the objective completes and rank 1 is yours in every game after.

What to bolt on

The community's list, checked against the item data. Six slots.

• Aim Assist (vehicle) · +20 % damage and 15 % attack speed; does not stack.
• Recoil Suppressor (vehicle) · +1 range and a 10 % slow for 1 s, 15 % once an Assault Engineer crafts it. Massive are immune.
• Recon Drone Module · detection, +1 vision, +1 range. The walker cannot carry a flashlight; this module, the rank 1 Flare Gun and Hawk Eye are its ways of seeing the invisible.
• Shield Generator (vehicle) · +5 armor and 200 shields; or the Minor Shield Generator (vehicle), 100 shields. Not both.
• Weight Reduction (vehicle) · +0.04 move speed. The community's page carries two.

Consumables

• Power Cell · 190 energy over 20 s, the vehicle's energy cell. Power User hands the walker 4 Power Cells where infantry get 2 energy cells.
• Nanites w13z · 100 life and the severe vehicle ailments cleared, at once.
• Magazines · 3 magazines a use. An Ammo Case holds up to 10 and hands them over when used. A reload takes 2.
• EMI Rounds · +30 damage against robotics, an Invasion drop.
• SAM Site Packed is on the walker's list but nothing in the map creates one.

SI picks

• Veteran with Battle Buddy: the wiki's first pair, for sitting on a hill and kiting with your buddy.
• Veteran with Heavy Armor for PMC: the extra life against grenades and rockets.
• Hawk Eye: the detection is the point, since there is no flashlight; the +2 range matters less, the guns already outrange the 22 sight at Main Weaponry 4.
• Quick Thinking: the wiki calls it almost pointless because it would not stack with Chassis 4. The reload code multiplies the two: 9.6 s becomes 6.7 s.
• Barbaric and Self-Sufficient: the SI panel refuses both for the walker. The wiki adds Intellectual to the useless list.

Looks

• Eleven of the camos have a walker skin: Default, Woodland, Night, Desert, Snow, Nano, OctoCamo, Purifier, Corrupted, Hell Scape and 2024 Voltage. Walker-only: the Cops camo, reserved for 19 players, four light colours and a no-light option.
• Type -meow or -roar in chat for a leopard or a tiger skin.

Where it cannot go

• Lift is filed with the jumps: the script refuses it, like the Predator's Jump, into the two No lift boots regions around the RA facility, with a stop order and an error message.
• Walking into the Jump1 region at the RA, or the Mayor Gate Jump region, blows up the walker or any biological player unit; both are in the JJump trigger group.
