Greetings fellow Doomers!

to various planets in the Milky Way to setup defense and stop the invasions!"

For some reason, I have always wanted to play an Invasion mod with Doom, Heretic, Hexen and Skulltag monsters. I thought it would be cool to see how the different species compliment each other. Over 10 years ago, I started on a simple Invasion map pack doing just that, but it wasn't up to my standards, so I scrapped it and started a new project in the same vein a few months ago. I'm pretty much done 2 maps, and have to release it now as I'll be a busy family man pretty soon!

This is a Doom 2 mod, and contains 2 UDMF maps, Doom, Heretic, Hexen, Skulltag, Realm667 and Diablo 2 monsters (not put into maps yet, as I wanted to make a secret level for the Diablo 2 bosses), Doom 2 weapons and new weapons (new as in, not from original Doom 2).

This is a newly built Invasion system that contains a lot of the great ideas from Stronghold, including spawning of weapons/items before wave start, customizable monster spawnin per wave, cooldowns for items so 1 player doesn't grab them all, and much much more. The PK3 contains a Readme with a lot of information in it if you want to read more!

This has been tested on Zandronum 3.1, and is intended for Multiplayer, but has been optimized for both Single Player and Multiplayer.

I hope someone enjoys!

Let me know if you have any questions, comments, concerns, etc.!

Cheers!

Can you post a Gameplay Video and Trailer on YouTube, so we know what it is about?

Sure thing. Updated the main post with the links. Quality isn't the greatest though.

Cheers!

Update:

Tested with Zandronum 3.2 with another player, and it seems to be running well!

Update:

Edited a few sectors in MAP02 to include more occlusion, as the map was too open from those points and was lagging a little bit when a lot of monsters were shooting projectiles. That has been resolved with more void space.

I didn't update the screenshots or videos though. Been too busy!

Cool!

I like the new invasion HUD. Doesn’t get in the way like the hard-coded one.

Update:

- Updated gameplay videos (as previous videos were not HD) and screenshots in first post!

- Few small detail updates to MAP02 like textures that needed to be fixed and such.

Edge case fixes:

- Corpse fade code - If player killed monster, then Archvile resurrected it, then player killed it again in quick succession, sometimes the corpse fade script would trigger twice.

- Monsters that spawn other monsters like PainElemental and Sorcerer1 (D'Sparil), if killed last would cause the wave to end pre-maturely even though Pain Elemental spawns 3 Lost Souls on death and Sorcerer1 spawns Sorcerer2 on death. Now it delays the wave completion when one of those monsters is killed last to account for the spawned monsters.

Thanks! That's what I was going for. I wanted to ensure that the player never got distracted by the HUD!

Much appreciated!

Update:

Expanded floor size for each step in MAP01 for one of the entrances to the building to allow monsters to walk in from that side.
