Hello Curators,

It's been a busy time since the launch of the Invertebrilliant Collection last month. Thank you to everyone who purchased the DLC, and welcome to all the new players who have joined us since the launch.

Based on the feedback from players over the last month, I've chosen a selection of features and improvements and put these into a larger-than-normal update. Let's take a look.

Replay base campaign with DLCs

One of the key bits of feedback I received about the Invertebrilliant Collection was the desire to play the base campaign levels with the DLC enabled. While this was possible with some save file editing, I can totally understand the desire for an official feature.

So that's what I've done.

As an added bonus, you can play with the Architect's Collection DLC too! DLCs with their own campaigns (Freshwater Frenzy and Deep Freeze) are not supported because these have too many separate technologies (freshwater, polar domes, abyssal etc.) to incorporate well into the base campaign.

I've curated the levels so that you have access to a different selection of DLC animals in each, to maximise variety. You'll also unlock the various Science-based objects during the campaign, when it makes the most sense from a level-design standpoint.

None of the objectives have been changed although there are certainly opportunities to complete the original objectives using DLC animals.

The prestige requirements for the levels remain unchanged, so you'll often find you don't need to use all of the animals available to complete each level. I like this approach because it offers the most flexibility and variety.

The one exception is 10. Megalopolis, where the prestige requirements for each rank are increased in line with how it works in Sandbox mode. So if you want an extra challenge, this is the one to go for!

'May eat or damage' warnings

In a complex aquarium, with several DLCs worth of animal content, the brain-fatigue of tracking animal compatibility can become a drag. To help with this, I've added warnings which appear above tanks when a predator may eat or damage another animal in the tank.

Players can continue to play in 'hardcore mode' by disabling these warnings in the settings. However, for most players, this handy warning should avoid those "ah dam" moments, while maintaining the compatibility puzzle that Megaquarium veterans know and love!

Copy from task bubble

This is a small addition that could save a lot of player time, so I wanted to draw attention to it. You can now use the Copy Object hotkey (default: c) while hovering over a task bubble (e.g. Orange Pellets appearing above a tank) to immediately grab the associated dispenser from the build menu.

This makes placing down the requisite dispensers after building a new tank a cinch!
