I like it, but don't give the player any exposition. Just drop them in with only the objective "Seal the Breach" and enemies incoming. The only sounds are alarms from the unnamed frame, the electronic death screams of the enemy, and a howling wind that drives the snow away from the Breach.
The mechanics would be spectacle fighter based (think Devil May Cry and Bayonetta) to allow for the weapon variation, ultimates, and fluid combat. You would start in the air in a running duel with a several airborne Types. You win the fight but get blown out of the sky by defensive emplacements. You can still fly, but now if you go too high enemy AA will make you pay. If you're skilled enough you can actually run the gamut never touching the ground, but you'd need to have already played the game to know the necessary moves.
On the ground, you'll be facing off against airborne attack units from above, generic ground units, and even burrowing units. As you advance the enemies become more advanced and difficult which doesn't change the fact your unknown character carves through them like a hot knife through butter. All the while the sickly yellow pillar of light showing the location of the Breach looms closer and closer with wind blasted snow pushing against you and lowering visibility. At the point visibility is almost zero all you see are the pulsing outlines showing terrain and enemies is when you first encounter a Type 2.
You finish the trench run bellow the enemy guns only for it to be quiet. Too quiet. You're under whiteout conditions with only a sonar like ability letting you see things. You kill a few more enemies when your HUD goes nuts. Phantom contacts all over on your TacMap, glitching on your objective indicator, and an ominous red warning of an unknown signature. When the ground under you literally explodes introducing you to your first Type 2. Cue a "Target the Limbs" boss battle with an ongoing interface screw.
If you're doing the aerial run, then there's a short cutscene of a Type 2 blindsiding you and forcing you to crash land. On the ground, another Type 2 will be waiting with two more teleporting in. The fifth will exploded out of the ground. Good luck, have fun.
After the Type 2 fight, you'll hit a loading screen before continuing into the Breach. The entire fight will be you descending into the center of the Breach and destroying the core. There are almost no basic enemies. Almost all of the enemies here functioned as elite enemies or mini-bosses in the prior level. After destroying the core, you play out run the fireball with every enemy still alive trying to stop you.
Cue cutscene with a Big BOOM and an appropriate shockwave. Garbled noises that might be radio transmissions are heard. When player control resumes the objective field is empty and the clue on how to continue is a waypoint marker in the distance.
After the player gets... let's go with a quarter of the way to the waypoint, the HUD again starts blaring about an unknown Higgs signature incoming. And it's a massive red blob on the TacMap coming right at you.
Welcome to the BOSS LEVEL.gif
I'm having trouble putting the ideas I have for the fight into words, but I think calling it the love child of the Senator Armstrong (MGR:R) fight, the Spider Mastermind (DOOM 2016) fight, and Shadow of the Colossus would be fairly accurate. During the fight on the side of the screen is a prompt showing the button combo to "Finish Him." Too bad the charge time is too long for you to use it until both you and the boss are almost dead anyway. When you complete the combo you going into a cutscene with showing the damaged Valkyrie raising her arm at the charging main gun of the boss and her screaming only for the scene to flash to white. In the white screen you hear the yet unnamed Wave Force fire and Sekhmet's death scream. As the screen fades back in, the broken radio chatter you heard since destroying the breach can be heard more clearly.
The unnamed Valkyrie takes off again and continues to the waypoint without looking back. As she flies into the distance to the game's theme with Sekhmet's corpse in the foreground the radio chatter resolves into voices shouting about how Saskatoon Breach is down and Sekhmet is killed as well. Cut to title card and as the theme finishes we see Koji stepping off the plane into Perth Academy.
P.S. phone typing is suffering.
