Darwinia is a classic indie game, an RTS on a large yet microscopic level. Very tron-like in it's intention and it pulls the theme off well. I highly recommend it, and it's "sequel", Multiwinia. The basic story revolves around you, a hacker, that finds a scientist's private server, that contains his experiment on creating a digital species (Darwinians). But viruses have corrupted the majority of his life's work, and you need to command his creations to free themselves from the malware and virueses that are destroying the world that the scientist has created for them. It makes you feel good when you have a victory, and mourn the loss when innocent souls are slaughtered on a mass scale in these epic battles.
Gameplay-wise, it has essentially no resource management whatsoever. But that is a good thing, especially for those that are just dipping their toes in the RTS genre, and just want action. You instead control the battlefield by initiating various programs and deploying them to fight the infection. as well as appointing captains of the local population of darwinians that rally those nearby to attack, move to a position, and such. The programs you can initiate to help fight your battles include engineers that collect dead 'souls' to be revived, and capture important buildings such as spawn points and traffic lanes. Then there are you direct combat commandoes, the squad. The squad is a group of 3-5 heavily armored humanoid soldiers that you can command to directly move anywhere, and you can direct their fire yourself, like in a top-down shooter. Upgrades can also allow them to lob grenades at your will, among other things. As I mentioned before, you can appoint a Darwinian to be a captain of sorts via another command. The final program is initiating an airstrike over a designated location, devastatingly ripping anything below (including your own troops) to pieces.
As you progress through the campaign, you can find boxes of previous research from the scientist, and tell him to research (essentially, upgrade) one of your commands, which takes some time but is useful. Upgrades include adding more members to a squad, allowing regular darwinians to throw grenades, adding another bomber to your airstrike runs, etc.
No buildings that you can control ccan ever be destroyed, and there is no resource whatsoever that you have. Darwinians spawn in waves, coming out of large buildings that you can take control of with your engineers. Your engineers can also pick up the souls of dead enemies and allies that linger after they die, to deposit them into these buildings that resurrect them.
As you can see from the trailer, the battles are massive cluster#$!@s of friendly and not so friendly darwinians, other enemies lke snaking viruses and spiders, etc.
The story is inspiring, the gameplay is unique, simple, and fun - I would recommend it to anyone, even those that don't do the RTS genre. To be honest, this a a gateway drug to the RTS genre. What I have to say to the customer who wants to buy this, is that they should buy this in the pack you can see below that has all the classic games from Introversion (The development studio behind this) and two of their soundtracks. Multiwinia is essentially the same as darwinia just without as much direct unit creation, but focuses on the aspects of using the darwinians in legions and using such strategies. You can get power ups too, that allow you to do various things like in Darwinia, plus some more. DEFCON is a good RTS that takes heavy inspiration from movies like 'Wargames' and the general Cold War scenarios that were hypothesized in the mid 20th century. You control a world power with nukes. You are just the general in the bunker, not any politician. As the situation escalates, you mobilize more and more forces that you place strategically early in the game. Then everything goes to ♥♥♥♥ as thermonuclear war breaks out. It really is more complex than what I'm saying here, and you might as well get it with getting the other games. Uplink is a neat, almost too-plausible hacker simulator inspired by the things you see in your average action movie.
So I would get all of their games for the value price when they are bundled, and it includes the soundtracks to two of them.
