As of the first question mark of your question, there is no PC version of Killing Zone 2 now, and there will be no PC version for a long time to come.
The reason is that "Killing Zone 2" was produced by the development team of Guerrilla Games of Sony Computer Entertainment, a European subsidiary of SCE, which means that this game was produced by Sony's first game developer and should be exclusively owned by PS3.
The "Killing Zone" released on PS2 is its predecessor, and the slogan when it was released was "Halo Black Boy". It can be seen that Sony's game is a work developed for the FPS of XBOX360. Therefore, "Killing Zone" must not be transplanted to its sworn enemy XBOX platform for sale, which is a brutal competition to seize the market.
The main reason for not launching PC version is that the economic benefit is small. The development cost of "Killing Zone 2" is high, and the PC version is not only expensive to transplant, but also the piracy of PC games is serious, and the sales volume of Z version is extremely low. Everyone doesn't spend money on the Z version, and Sony is likely to lose all its money.
Judging from the distribution law of Sony PS3 games, the probability of launching PC version should be full platform >: exclusive to PS3 and XBOX360 > exclusive to Sony. When dual-platform (PS, XBOX) games sell well for a long time, Sony will consider transplanting its PC version, such as Biochemical 5 now. Please note that "Killing Zone 2" is monopolized by the first party, and the probability of transplanting a PC is even smaller, which is almost impossible from the experience.
LZ now wants to play Kill 2 instead of buying PS3, and the only way is to get the simulator. However, there are still many problems in PS3 game simulation at this stage, and it will take a long time.
As of LZ, the second question mark (although LZ didn't write it. . . ) So far, the development of "Killing Zone 3" is very possible on this issue. You can see the shadow of the sequel from the end of the story of Kill Zone 2. In addition, judging from the popularity of the second generation, the "Killing Zone" series is likely to become Sony's next cash cow.
As for whether LZ's next work will land on PC and XBOX, I have made it very clear above. If it is still produced by the guerrilla game development team, it is likely to be monopolized by PS.
Moreover, anyone who has played "Killing Zone 2" knows that the most attractive part of this game is its online battle. The ban on piracy detection on XBOX360 will greatly reduce the entertainment of Kill Zone 2, and the launch of PC version will lead to the rise of a large number of unofficial online battle service platforms, which will take away a large number of players on PSN and affect the sales and popularity of the host. Sony will not allow this to happen.
As a supplement to the LZ problem, this news is unofficial and can't explain anything. It can only represent people's reasonable guesses and good wishes based on the status quo.
In addition, I guess Sony's next series of "Killing" games should be on the PSP platform, and then "Killing 3" on the PS3. Two generations of games on the same console will not come out continuously without special circumstances, and there must be a certain interval, which is also to ensure sales.
What I said above is not only aimed at the game "Killing Zone 2", but also applicable to the problem of PC porting to other PS3 games. When encountering problems, LZ is measured by these laws, which are basically close.
