About engine, I believe Omega might have more to say to this matter, but I can say that engine is able to support this kind of combat (talking about one man squad fighting in CQB) but omega simply cant make it better then it is with given tools.
I am really glad that you noticed this elevation changes, its basically just an illusion of using ladder for example. I tried to deliver something more what you cant see in ordinary game experience in MP. Main problem with MP maps is that there is too much destruction and there is incufitient number of objects suited for this kind of game play manipulation (making ladders, platforms and stuff like that). I tried to implement this feature in to normal 1v1 MP map called "Ruse" (its in my workshop if you wanna take a look) but appearantly it wasnt what players wanted. So what i think is that this feature is suited just for compaign maps.
About save game feature, i think that different coding which is core for Omegas maps is also main problem that makes game crash after loading in to game. I might be wrong but I believe that Omega will respond too and correct me.

感谢你的评论。

对不起，我住在国外的时间太长了，我的中文不好。我会用英语回复你的评论。谢谢！

Firstly, thank you for your comment! It is very much appreciated! Also thanks Kbal for answering! :)

Secondly, to answer your question about the 'save game' feature. This is both by design and also by limitation. Before I start a project I always do an analysis on what is unique to deliver. The more innovative and unique it is, the better.

By design, we wanted to make a campaign that is extremely difficult but very rewarding when you finish the mission. As such, the best way to do this is to disable the 'save game' feature. Otherwise we risk making the missions so hard it's impossible to finish for everyone.

By limitation means I am unable to code in a save feature. Every time I try to code in the save feature the map crashes after I load a saved game. This is something I am unsure about as I don't know what is causing the loaded game to crash.

Overall, the unavailability of the save feature is mainly a problem that needs to be solved by coding. If I do not receive help with the coding I cannot introduce the 'save game' feature unfortunately.

Once again, thank you for your very thoughful comment. Please fell free to add your comment to every mission. I would like to see more! :)

@Opulent Omega,感谢你的回复。你说你中文不好，但我不知道你是阅读中文困难（如曾经认识许多汉字，现在不认识了），还是以汉字写作困难？如果你阅读中文也有困难的话，我可以把下面的回复文字全部转换成英语。不过，我的英语水平估计没你好；目前，我以汉语写作与交流的效率要高于以英语写作或交流。作为尚未出过国且年纪比你小的人，我很好奇您的经历及您目前的居住地或职业状态，这可能对我会有借鉴或教育意义；若您认为这会涉及个人隐私，这里公开场合不方便透露的话，那当我们同时在线时，我希望我们可以进行即时聊天( If you have trouble in not only writing with Chinese but also reading Chinese, I can translate below reply words into English. But it seems my English is not as good as you. Currently, the efficiency of my writing and communication is higher when I use Chinese than using English.)
1.如果我时间允许的话，一定会对你本系列所有任务进行评论；不过，不知你是否注意到，其实我的这篇评论就是针对"Iron Heart"全系列任务的一个总体评价；当然，其中对你在士兵位置、可驻兵的建筑设计等创新方面的赞赏的确仅针对该系列的第四章回，因为毕竟无论从剧情发展还是技术创新方面来看，第四章回目前是你这个系列任务创作成就的最高峰。然而，我可以考虑将这同一篇评测同时发布到你该系列任务各自创意工坊页面的讨论区，并且我可能还要对评测进行完善补充与稍加改动，因为目前我还没有对该系列任务中的剧情进行评论。
2.若不考虑技术限制方面的因素，我不认为你故意撤除“存档”功能以此刁难玩家的想法是可取的，因为这样的确会浪费许多只想了解剧情，但不奢求“一命通关”的玩家的时间，我认为，将选择权完全交给用户才是最好的方式——想考验自己能力，不畏艰难，不怕浪费时间的玩家完全可以自主放弃“存档”功能，从而逼迫自己“一命通关”；而那些只希望体验剧情的寻常玩家，则只需轻按"Save Game"按钮即可节约时间——这便是我心中理想的模式。我知道，2代的《英雄连》比前一代在模组功能支持度方面收紧了不少，这不是社区乐于看到的；当我有空时，我将会继续向Relic公司提建议，并质问他们。不过，由于我发现你很有制作游戏或模组方面的天赋，却遇上了《英雄连2》这样极差模组功能支持度的游戏，我着实感到遗憾；所以，在这里，我想向您推荐另一部伟大的游戏，那便是《Arma 3》，首先许多人对这款游戏存在误解，甚至敬而远之，就是因为这款游戏是讲究严肃军事模拟，有较大的学习门槛与上手难度，但其实，它的游戏性完全可以通过其超自由的模组开发来改变，甚至完全可以被改编成像《Call of Duty》那样的娱乐向射击游戏，或是如《GTA5》那样的自由开放沙盘世界，从而降低其严肃性，增加其娱乐性。《Arma 3》可以说是我见过的，也是公认的对社区模组制作者最开放、最友好、最自由的少数几款游戏之一。《Arma 3》也是著名且强大的军用训练软件《VBS 3》的民用版本，而《VBS 3》则是捷克共和国波希米亚工作室(Bohemia Interactive)提供给北约各国，如美国、英国、新加坡等国的军用训练软件。目前，军用版本"VBS Blue"计划已实现全球地图（即全地球模拟），《Arma3》尚未加入这一强大功能，但未来《Arma》系列很有希望将可交互的空间范围扩展至全地球乃至太空。不过，其实目前《Arma》系列早已成为游戏界拥有最广袤地图规模的屈指可数的游戏之一了。不过，《Arma》系列主要是第一人称与第三人称（可互相切换人称视角）的海陆空战术射击游戏，不知你除了RTS即时战略类游戏，是否对第一人称或第三人称射击游戏有兴趣？不过，《Arma3》也不是一点即时战略元素都没有；首先，若作为指挥官，其对小队的指挥系统细节挺丰富；还有，官方加入了称之为“宙斯”(Zeus)的游玩模式，扮演“宙斯”的人可以有限度地操控一局中的战场的各方面元素；社区玩家中有位叫"Gunter Severloh"的人发布了一个叫Ragnarok'44 mod (IFA3)的模组（链接见文章最后的“附”），该模组就是将即时战略RTS元素添加给《Arma3》，让你可以像玩《英雄连》那样以“上帝”视角进行游戏操控，但是该模组还很不完善，存在许多Bug就是了。我自己也准备向Bohemia公司提出让官方加入完整RTS功能的请求，因为在我看来，一个完美的军事游戏应当是RTS与FPS元素的完美整合。（其实，目前另一款游戏《Call to Arms》已经实现了上述目标，但其游戏引擎不如《Arma 3》的强大，至少在地图规模与飞机飞行轨迹模拟方面做不到《Arma3》的级别；其实早在《Call to Arms》的前辈《Men of War: Assault Squad 2》中就已经实现了将RTS与第三人称射击元素同时纳入同一款游戏中，但《战争之人》系列的继任者——《Call to Arms》则更进一步，将RTS与第一人称及第三人称射击元素全部纳入同一款游戏之中。）所以，你如果想继续模组制作的话，我非常推荐你去尝试以《Arma3》或《Call to Arms》或《Men of War : Assault Squad 2》等游戏为平台来制作模组，这会使你的模组比用《英雄连2》做更精彩！不过，若论模组自由度与工具性能的强大性，我最推荐《Arma3》；但就目前若仅仅做RTS即时战略模式的模组的话，我最推荐《Call to Arms》和《Men of War : Assault Squad 2》。另外，不知你对除了二战以外的其它时期的战争是否也有兴趣，因为《Call to Arms》与《Arma3》原版都是描述近未来时期的现代战争的，只有《Men of War》系列主题为第二次世界大战（且其与社区能提供的单位种类远超《Company of Heroes 2》）；不过，《Arma3》的社区里有一个出名的以二战为主题的模组，叫"IFA3LITE"（全称是"The lite version of Iron Front for Arma3 edition"）（它的链接我也会附在文章最后），该模组原本是一款由AWAR独立游戏工作室基于《Arma 2》的引擎开发的独立游戏《Iron Front : Liberation 1944》（该独立游戏本身继承并包含了《Arma2》（《武装突袭》系列）强大的任务与地图编辑器），包含德军、苏联各自阵营的单人剧情战役，DLC "D-DAY"包含了新阵营美军的单人任务，该游戏也有多人游戏部分。而"IFA3LITE"模组则是社区玩家在征得原开发者同意的前提下，将该独立游戏转变成专门为"Arma3"平台提供的免费模组，且在技术性能方面从原《Arma 2》时代的引擎升级至《Arma 3》的新引擎。我向您推荐"Iron Front"的原因可不仅仅是因为它是二战主题的模组，更重要的原因是由于《Arma3》模组工具的强大自由度与兼容性，你完全可以利用这些"Iron Front"里的二战素材在《Arma3》的编辑器里创造出属于你的精彩二战主题任务或地图！你可以将你在《英雄连2》的"Iron Heart"系列任务剧情照搬到Arma3平台，而Arma3的优势是至少可以让你加入更多如飞机或海上舰船的元素以及非常巨大的地图。期待未来我们可以进一步交流！（注：以上推荐的游戏均可在Steam上通过搜索相关名称找到，这里我就不一一给他们也做附录了。）

In future maybe English is better haha! :)

To be honest the lack of a save option in the series is more due to technical limitations rather than a fully intended feature. We did the best with what we had and in consideration of a lack of a save feature, we instead chose to make a 'challenging' campaign for players to finish. I suppose this idea works for some players, as the Dark Souls series of games show.

I appreciate your suggestions for modding in other games but right now I simply do not have the time to get into too many projects. I am not only a gamer but also work in fairly time-consuming jobs and also have other many personal projects I work on. Modding maps in CoH2 is like a simple way for me to 'refresh' my innovation side of my brain. It make innovating fun and interactive, which is not something that usually happens in any other setting when it comes to innvoation to be honest.

Your review is very long and I feel my reply does not do justice to your effort. What I will say is I am familair with almost every single one of your suggestions and I know what their communities and games can offer. However I chose CoH2 as I thought it was the most fun in the least time-consuming fashion for making maps and mods. But thank you for your kind suggestions!

Please do continue to review all my creations as you see fit. I have read your entire reply and feel you give many great insights so clearly you know your games and gaming communities! :) Please keep in touch and continue to leave your brilliant reviews as we make more maps and mods!
