If you do not understand it, because the Oil Rush - Naval Strategy Game  game is quite new (2012). Oil Rush - Naval Strategy Game is clear  manifold startegy like Red Alert. The difference Oil Rush of war at sea.  Create a Strategy game fan game that I think need to try to have this  solid graphics. 
The game was created by the Unigine Corp. studio and it's using the  Unigine technology. Maybe these names are not too familiar, but some  hard-core gamers Might Recognize them from other instances.
Unigine technology was used in an amazing DX11 benchmarking software  called Heaven, the which also uses OpenGL 4.0. Some Unigine Engine tech  demos are included in the Phoronix Test Suite as well.
However, the engine was actually already used, by third-party  developers, once in syndicates of Arkon, an MMORPG, and Dilogus: The  Winds of War, a not-yet-published RPG.
Story and Gameplay
Even if It Might seem redundant to Provide a story for a tower defense  game, the developers have tried to offer some kind of background for the  gameplay mechanics. Given the fact That everything takes place at sea,  gamers need some clarifying for this environment, as the one Provided is  just not enough.
The action takes place in Oil Rush sometime in the future, but it's not  clear whether it's an alternative timeline or our future. Mankind has  barely survived after a nuclear war hastened That climate changes.  Because of global warming, there is no longer a land mass and everything  has been engulfed by water.
Some pockets of humanity REMAIN to carry on with the civilization still  powered by oil. The entire economy is oil based and people only live  around oil wells.
The player assumes the role of Kevin, a young graduate from a military  academy, WHO strives to follow in his father's Footsteps. Immediately he  is given a job to defend his colony from raiders' attacks, and so his  adventure begins.
Oil Rush is Divided into chapters, each one consisting of Several  missions. More or less, every mission is almost like a skirmish map in  the which the player is pitted against an AI foe. There are some minor  variations, but only to introduce Generally some new units or  technologies.
The learning curve is somewhat steep. The first few missions are easy,  and players get the chance to witness how the engine looks good.  Sometime during the second chapter, the difficulty changes abruptly,  leaving players with a single valuable tactic, a Guerrilla war.
Every map starts with the player controlling one or more platforms. Each  platform is used to spawn a fixed number of Certain units. You can not  build the units and the platforms can not be destroyed, at least not  with normal means. They are Considered too valuable and are always the  object of capture.
The normal platforms, with the exception of oil rigs, can have defenses  built around them, in five predetermined slots, consisting of miniguns,  cannons and sol-to-air rockets. Every single one can be upgraded and  all must be destroyed in order to capture the platform. Players can not  do anything during an attack, besides Speeding up the construction of  replacements.
There is also a small tree research available, the which uses points  gained in battle. Most of the technologies can be researched fairly  fast, at the beginning of each map, but They are not Carried from one  folder to another, the which is kind of annoying. However, there are  always more points available than can be used.
Graphics
Oil Rush is an amazing looking game. It's on par with developed  everything these days and the fact That everything takes place on water  was a challenge for the developers. Water is one of the elements most  difficult, to replicate in a game Because players can easily spot "fake"  looking textures.
The Linux platform is not known for being friendly with gaming  development, and there are only a few games available right now That can  be compared to Their counterparts from other platforms. Moreover,  beside the graphics, the engine benefits from a pretty good physics  technology the which makes the world a lot more tangible and believable.
Some gamers have said That Oil Rush is only a "tech demo" to  demonstrate the power of the engine, with little to no gameplay value. I  think not only That this is an amazing engine, but that the game Itself  is solid and has quality written all over it.
Multiplayer
As far as I can tell, the game has a simple multiplayer mode, but it  does not work on Linux. After some research on the official forums, it  seems a That only Steam versions of the game can use the lobby function.  The other Linux users can not see games hosted Because there is no API  Implemented to resolve this problem. Needless to say, there are quite a  few angry people on the forums Because of this.
All is not lost, as users can still join other people's games by  entering the direct IP of the host, but this would mean That They Could  They only play with people already know, like a LAN game. Oh, and the  IRC proposed solution on the official forums is not really a solution.
As I said Earlier, users can also create multiplayer sessions, for up to  four players, and They can choose from a selection of Various maps. A  quick mode is also available, aka skirmish for older people, so you can  experiment with the multiplayer online gaming maps.
The Bad
First off, I want to make it clear That Oil Rush is an amazingly fun  game to play. Even if there are a lot of problems, correctable through  future updates, I would still recommend it in a heartbeat, regardless of  what I'm about to write.
The main problem I encountered was the difficulty steep climb in the  second act. All of a sudden, the maps Became really hard. Maybe I'm just  set in my Airways, but this is not the first or tower defense strategy  game I've played. I understand That PC games will always be a little  harder and I really missed the days when games were impossible to finish  Sometimes, but a strategy game should have an incremental difficulty.
The second issue is related to the gameplay. Users do not actually  control the units, but the platforms. Once you send a group of ships to  another platform, until They get there, you can not Interact with them  in any way. I've restarted countless times maps Because of this single  issue, and Because of the unit selection system, I'm not really sure  this can even be fixed.
The third problem is of course the multiplayer mode. No lobby on Linux  That means it is a lot harder to find gamers to join you. For instance,  my friends and I have different schedules and it's hard for me to find  them online. I really hope this will be fixed sometime in the near  future.
The final issue is actually a minor one. I hate the fact That researched  technologies do not follow me from one folder to another, in the  campaign mode. I feel silly searching for everything all over again, in  every folder. I Realize That it's part of the gameplay, but that does  not make it right.
The Good
Beside the amazing graphics, the entire game is Presented in an  atmosphere That lures you into playing. Whenever I "rage quit" a game, I  would restart it almost Immediately Because of the quality atmosphere.  Maybe it's the lightning or the color pallet, but I enjoyed every moment  playing Oil Rush on Linux.
The other thing That got me hooked is the gameplay concept. Oil Rush is  not really a strategy game per se and not actually a tower defense game,  but rather something in Between. However, the combination is a  Successful one and I do hope the game will be pushed even further  through some DLC or expansions.
Conclusion
Even if I watched the development of Oil Rush for almost a year, I did  not see it coming. It's a beautiful game, with a core mechanic That will  probably start its own genre. It may have some faults, but none of them  is too great to Prevent anyone from playing or enjoying it. It's viewed  mostly extravagant like an indie game, but if this is not A + quality,  then I do not know what it is.
Every Linux fan out there has to Realize That the days when games were  for "other platforms" have come to an end, and the Harbinger of the new  era of gaming on Linux is Oil Rush.
