Open-Source reimplementation of Westwood’s Command & Conquer: Red Alert game engine, updated to use the hardware acceleration of modern video cards using OpenGL and OpenAL for sound playback. It runs natively on Windows, Linux and Mac OS X. The game was designed with modifiability in mind, but is not identical to the original. Campaigns and mods made for the legacy game won't work out of the box.

This unstable playtest adds the long-awaited AI improvements. Bots will now be significantly more fun to combat and act lot less brain-damaged. The most changes are done in enhancing the GUI usability and re-balance the Tiberian Dawn mod. Have fun and happy testing. Please report problems at

"MCV are not buildable anymore to workaround base-walking and turret spam"

An FYI, you shouldn't disable a feature just because it's cheese. If Blizzard did that with StarCraft, Protoss wouldn't have Pylons or Cannons anymore. Zerg wouldn't have Zerglings, etc.

Base Walking is a pretty legitimate and expensive strategy. On the chance it works, you win. But it can usually be scouted ahead of time and can easily be prevented.

As well as punishing players that do this, your also punishing players like me that just like to build nice bases and building multiple ConYards helps with that.

Anyway, speaking of building bases, OpenRA needs a Singleplayer save feature. =)

Aside from cheesing, a forward base can be an essential tool in normal games too (for production and repairs), given the map is big enough or consists of seperated islands. Not to mention that "hidden" backup bases can be a golden investment. I would prefer not to have barracks-creep my way to a forward position or start a large scale ferry service when an enemy turns out to be better defended than I expected. Unless you give me Supreme Commander styled transports that can be used in combination with waypoints to create automatic routes, then I won't mind ;).

The feature will be fixed soon.

If you want to expand your base, you still can. Just redeploy your construction yard into an MCV and move it to the new location. You don't have to worry about losing your MCV too much because it will pop up in your next crate if you lose it. (Crates come fairly often).

The reason it is temporarily disabled is that basewalking is insanely good with multiple build queues. With say 5 MCVs (only $2000 each in OpenRA), you can save up many turrets in your build queue and deploy them all near an enemy base at the same time. Keep in mind that C&C 95 did not have multiple queues, only sped-up production, which is not as powerful.

The future solution will incorporate a maximum build radius around construction yards, and probably a cooldown time before placing new structures around an MCV.

Then solve it by using the original stats for units.

I'm fairly certain that in both RA1 and C&C, MCVs were 5,000.

Also, why give Nod the Guard Tower? They have the best Anti-Infantry stuff.

You CAN'T balance games by Rock/Paper/Scissoring. You have to consider what is already in the game.

Also, instead of creating stupid limits just change stats. Weaken defenses. Or even remove the build queues for the normal games and let people use them for their own mods.

In Red Alert 1, the MCV cost was lowered to $2500. This is what "should've been" all along. $5000 is absurdly high for a vehicle, and makes base expansion prohibitively costly. The new cost as it is is fine, and around where it should be.

OpenRA will have both a "C&C-Classic" mod and a C&C mod for OpenRA. The C&C-Classic mod will have *exactly* all the same values as the original game. If you want an authentic experience, go play that one. Meanwhile, the main C&C mod is modernized and made to reflect what years of RTS experience after C&C has taught us. It's much more fun, while still being true to the spirit of the original.

There is no need to weaken defenses. That would actually ruin things, because the game is quite well balanced as it is. Changing the stats of multiple units is far more radical than simply imposing a restriction on how far you can build from your construction yard (about 10 tiles away). For most games, the player won't even notice.

We have to face the fact that the original game just wasn't that well thought out for multiplayer. It was one of the first RTSes ever that supported multiplayer, and it was rushed to market before being fully polished. Its focus was on singleplayer. Multiplayer was not really refined or balanced--it was made in an era where they had little RTS experience. The fact that Nod had no guard towers in the original doesn't mean they should be removed. They actually fit quite well.

Once you try playing with the cooldown you will see it is fine. It will only be around 8 seconds. It will have no noticeable effect on gameplay, except for players who try basewalking across the map very quickly.

I agree make it optional in the options to choose if the player wants it enabled or disabled. Removing core features is always a bad thing.

Also not sure about the cool down thing. Sounds like an easy work around on cost of game play. If at all limit the maximum turrets someone can have maybe 15-20-30 per player.

We support a build limit for missile silos and heroe infantry so this might be a sensible approach for modders.

I still can not get the game to work... it worked on my old 32bit laptop and this laptop has a way better processer, grpahics card, more ram and it is also windows 7.
