So something I think this game needs is a direct influencer for the game pacing, like optional objectives ‘inside’ of the tilesets that change the gameplay.
For instance, maybe there is a Chaos worshipper or a nurgle spawn buffing the tile enemies, so you need to find and end them.
Or maybe there is a massive sector power surge and there are zones of electricity creating danger zones, and you can turn it off by blowing up or hitting a switch, with either choice affecting the zone (e.g. Lose lights, access to certain things, etc).
Or there is a tear in the warp, and those who are there can enter the breach to seal it from the other side, gaining a bonus at the end, or during the rest of the session, having weakened the area of enemies, or future bosses will have a 25% hp removed.
These wouldn’t be the current modifiers, like more enemies, lights out, the dogs, etc etc, it’d just be ‘additions’ to levels, so instead of retracting any content it would add additional map layout content and features. Harder parts would be the outdoors areas, but maybe do something like a quick local AA disable and some aircrafts can pass by doing gun runs.
Aight im outta ideas now, peace.
