Beta version 0.1 of Alien Swarm Single Player (SP) is now live.
the following features are available:

- all official maps and addons available to play through Offline Practice Mode
- configurable automatic team selection allowing mapper to assign team spots for each map and force player to spawn in a specific marine (skips team roster screen and boots straight to map)
- can spawn bots elsewhere in map and bring them into and out of play when you wish (to be used as power-ups etc...)
- Weapon strip allowing more half-life style weapon discovery
- instant health and ammo pick-ups

I'm quite stunned at how this mod has taken off. Currently we're standing at 150 downloads and it's rising by the day.

Obviously the mod had a very simple goal and I achieved that quite quickly. It does what it says on the tin!

The question is... what now...

I really would like to hear from you what other features you would like to see in future releases. Here's my thoughts so far...

- A save game function
- An action replay function (review your performance and the action from a different POV)
- Single marine maps (currently working on these as you can see from the screenshots
- Stats tracking against previous attempts at a mission (compares your stats against the last time you played that mission)

Let me know any ideas you have, no matter how whacky or out there it may seem. Anythings possible.

This mod isn't dead exactly.. it just does what it says on the tin.
It allows you to play Alien Swarm maps in SP mode. The problem we have is that there are few maps designed for a single player experience.

At the moment it works and people are using it. The next phase, so to speak, would be to simply create some maps to go with it. I'm currently wrapped up in my HL2 project so may come back and create some maps soon.

If however someone else wants to create a few maps to be played with this mod then please feel free... It's great fun to create maps in my opinion and you don't need to know any coding.

hopefully this mod is not dead I see a lot of potential and would like to see progress in this mod. If you need help I guess I can help you but I dont know anything about coding or that stuff. But anything else I can help you with just let me know.

Is it possible to have bots in multiplayer? Me and a friend and 2 bots? and can I add more bots than the max limit?

Reply Good karma Bad karma+2 votes

It looks amazing and is a great idea. Don't understand why it is not already in the game though. Just about to try it out.
