1Battlefield

A lot of the difficulty in this stage comes from properly handling the prompt-bullying. What is prompt-bullying? Well, the first level acts as a tutorial. You have to do specific ations in a specific sequence as indicated by prompts. But not too fast, because if you do an action before the prompt appears, it won't count. This makes the level frustrating to play, when you want to rush thru everything and are not in need of a handholdy tutorial.

Start

Prebunker

You're stuck watching a Knightfight for 15 seconds. Viola will talk to you. Turn around and as soon as you move, rush down to the bunker entrance and position yourself at the lever box. Viola will talk some more. As soon as the lever box opens, flip it and position yourself in front of the ammoboxes at the range.

Range

When grabbing ammo, it's easy to do this too fast and throw the ammo on the ground. Don't do that. Hold out both hands to grab two magazines at once. You will have to wait till prompted, before you're actually allowed to grab them. Be careful that when placing them in your ammobelt, the belt appears blue, not red. Now grab the third mag and position your left hand ready to grab the ammobox, once prompted.

Now wait for the prompt "Look down at the bolter at your hip" and do it, then "grab the bolter from its holster", do it, then "Release the Bolter by your hip to holster it again", do it, "pick up bolter", do it, "Hold your Bolter to your belt to insert magazine" and wait for the icon of the magazine to change to an icon of your belt and then do it.

Now shoot three targets five times, reloading once between each cycle. Immediately holster the bolter and proceed to the crate, and wait out "Holster your bolter" and "You have holsters on both hips". Once the prompt "Grab more ammo from the crate behind you" comes, you can open the crate and do just that. (careful not to spill any). The prompt "Join Viola to proceed" appears and you move in position at the leverbox.

Trench

First Section (Entrance)

One Harry on the left, one on the right. Then another on top of the trench. Position yourself in front of the invisible wall and wait out the little rhino-explosion-dead-harry event before you're allowed to proceed.

Second Section (Melta Bridge)

One Charry jumping from the bridge, one coming toward you under it. The prompt "Steady your aim by gripping the Bolter with both hand appears". Three enimes above you, two appearing more to the right, another to the left of them. Holster Bolter on right hip, grab the melta and ammo, put Melta on left hip. Wait for the prompt "You have a holster on both hips" and draw both weapons and wait for the prompt "Try holstering your weapons now". The prompt "Use the Meltagun to destroy the Barricade" appears. Draw both weapons again and melt the barricade.

Third Section (Post-Barricade)

Rush forward and oneshot the Nerd. (3 Melta ammo left) You're facing another bridge and are blocked by an invisible wall now. 2 Cherries rushing you down, 2 more on the bridge. Probably doable to oneshot all four with one boltershot to the barrel. (so far, I only managed the triple though) The invisible wall is down and you can proceed to hit the next invisible wall just after the bridge. A next Harry spawns on the bridge, which you can bolterkill from below. Face the invisiwall again and headshot a Harry by the barrel and hold down the trigger to spawnkill the Harry who appears in front of the barrel and then kill another Harry that appeared on the bridge. Note: On the right above you, there sometimes spawn enemies which can be oneshot by explosive barrel. But they did not seem to make an appearance in my 7:25 run. Maybe Orphelia killed them, whilst I had my back turned?

Fourth Section (T-Section)

Kill one cherry coming from the right. Kill the Harry behind the barrel and doublekill another bridge-Harry and bridge-Nerd with a barrelshot. Kill another Cherry coming from the right and then another one spawning on the bridge.

After Viola says "Orphelia, guard the rear." go down the right path, kill two more Harrys in front of the little barricade on the ground and one on the bridge above it. Holster your bolter, turn around and take another right oneshotting another two Harrys at once (2 Melta Ammo left).

Fifth Section (Rockslide)

Proceed a longer stretch, where you grab some Melta ammo with your right hand and hit the invisible wall, where the rocks fall and block you off from Viola. Once you hit the wall immediately proceed back and take a left to the barricaded path again. Oneshot both Larrys with one Meltashot each (0 Melta Ammo left), bolterkill the Larry on the bridge and load your second Melta magazine, after which the barricade explodes for no apparent reason, clearing the way.

Sixth Section (Fight for the Sacred Ladder)

NOTE: You will have five Meltashots loaded and another magaizne, should you need it. I haven't done this fight optimally myself yet, so figure it out. Maybe you don't need the extra Melta magazine at all, which saves more time.

Go past the barricade, kill 3 Harrys clustered together, then 1 Harry + 1 Nerd turn around 2 more Harrys turn around again 5 Harrys above you, 2 (one in the middle one on the right) will stay up which you shoot first, giving the other 3 time to face you on the ground and charge into your Melta Once that's done drop the Melta, holster the Bolter and go to the ladder on your left. Note: In my 7:25 WR, I've climbed the ladder competently, but there's probably some crazy onehanded flingstrat, where you don't holster the bolter, that saves a second or so.

Rhino Adventures

Securing the Rhino

Shoot the first charging Harry on the left, swing to the right and kill Harry on the right. Shoot the barrel to kill the two chargers and drop the bolter. Now climb the Ladder up the Rhino and grab the Stormbolter.

Stormbolter Time

Group of three on the left, kill only the rightmost 2. (the third will get killed by the droppod)

A pair of two behind sandbags, Orphelia likely kills one of them. Kill the other and avoid blowing up the barrel. Swivel over to the Droppod and kill the 2 Nerds. Swing back to the barricade and get a triple kill with the barrel. Then on the right bank, there's a group of three. (in my WR, Orphelia triple-killed them by shooting the barrel herself, but I don't know if that's consistent. Do it yourself, if necessary) Kill the next 2 Nerds from the droppod on the right. Take out the two Harrys flanking Orphelia from the left at ground level. This should be enough time so that the group of three just above is in position for a triple-kill-barrelshot.Swivel to the last droppod and take out the last two Nerds. Swivel to the right bank again and take out the last three Harrys.

Farewell to Best Sis

The other Harrys start to run and can be ignored. Position yourself facing Viola and wait for the bomber to bring her closer to the Emperor. Rush down to her as fast as you can and from then, no more inputs are required.
