OpenSA (SA stands for Swarm Assault) is a real time strategy game that requires you to control huge swarms of ants, beetles, spiders, scorpions or wasps in a desperate attempt to control the landscape. No resources, no population cap, just build your army and smash the enemy!
You do not have to build anything, all you need to do is to start instantly producing units and conquer other colonies. Easy and simple!
The original game is hardcoded to 640x480 resolution and some of its mechanics are nowadays obsolete. That's why the idea of bringing this game to OpenRA engine has been born so everything can be either fixed or improved in the brand new engine.
The project's goals are:
Long time no see. As usual the progress was quite slow. During that production time, a lot new features were developed which I hope you will like. So without further ado, let me show you what you can find in the latest release!
A lot new missions were created. Many thanks to Hooet (교니체) for your support!
Have you ever played Swarm Rampage, the sequel of Swarm Assault? Whether the answer is yes or no, the idea for this new structure come from that game. This new building increases unit production in all team colonies by 10%. Exclusive to only custom levels.
Another new structure which the idea was taken from Swarm Rampage. It increases firepower of all team units by 10%. Exclusive to only custom levels.
Want more? Here’s Tesla Defense Tower, loosely based on the one which you can find in Swarm Rampage.
Since the very beginning my original plan was to make Scorpions Defense Tower with only one spear weapon. I decided to finish what I started, so now you’ll be able to place in maps scorpion defense turrets with either two or one spear guns.
Beetle Defense Tower got some new art. Mainly due to fit its size to the 1x1 tile.
OpenRA default HP bars were replaced with new ones, more faithful to Swarm Assault ones.
This update adds a new creep plant to the roster. It’s a Poison Mushroom for swamp world, as usual, it’s based on Swarm Rampage’s mushroom. This plant has been in the project for a while but I finally decided to finish it. The original idea was to recreate the plant from SR game, especially how its projectile worked. But after some thought, I decided to give to it the cluster warhead.
The original Dragonfly artwork has a lot of holes in its sprites. It's rather minor change but always welcomed.
The sidebar was updated to be more similar to the original Swarm Assault sidebar.
Also for those who are interested in importing legacy maps from Swarm Assault, I made a tutorial how to do it:
And as usual, I’d love to thank Mailaender and IceReaper for their help. Moveover, I’d love to also thank Hooet (교니체) for creating new custom missions and testing the project, you rock!
A new version of OpenSA has been released. It's full of new features!
A hotfix release which fixes quite big issue in map editor. Plus adds other minor fixes.
A new release which adds a lot new goodies to the game.
Another version which does some balance changes, adds additional mission and fixes.
This is a quick hotfix to solve some glitches and balance issues. Moreover, this version adds two new custom missions.
A new version of OpenSA which has 100 missions and a lot of new cool features.
Another version of OpenSA. It adds 31 more missions, does again balance changes and fixes some important issues.
I'm not sure if anyone else has already asked, but are there plans for adding Swarm Rampage in the future by chance?

Hey! It's very unlikely to happen as IceReaper user would have to reverse engineer game asset containers for me and I am not so experienced with that game either. But as some say, never say never.
Hi, I released a playtest version of OpenSA. I still want to add a few changes here and there, so expect a new proper version in 2023.

Hi, do you plan to translate this game into Spanish, for example?
Hi! Only English language will be available. You can translate stuff on your own if you wish to do it.
Hi, game cant detect my installation or iso. Is there a way to manualy point the game to the folder with original game files?
Hi. Just let it download all needed assets once you run the mod for the first time.
Hi, any chance tom add random generated maps like in original games? I really appreciate editor, but i miss fast random generated maps.
Hello!
Nope. No chance. But OpenSA can import original Swarm Assault maps, that's how all missions were recreated and some extra skirmish maps.
If you are interested in that, DM me directly, I can provide steps how to do it (it's not that hard, but requires some extra work, but it's easy once you understand it).
Here is some gameplay from this mod, feel free to use the footage for whatever!
