Early Access Review
Strange situation. This game was released more than 6 months ago but she still has very main problems that were in the beginning. Developers focused on adding new content, application of new ideas, improving technical side (high resolution, controller support) but main gaming base remained unchanged.

I will not write anything about the balance of the game. He is the same as in HD Encounters. I have not noticed any changes. Only kleers and buls are moving a bit differently - they are harder to kill and they are more dangerous than HD.

Serious Sam Classics: Revolution have both Encounters. A few days ago was added new difficulty named "I am Ugh-Zan". The same us "Serious" difficulty but all enemies have 1,5x health and each enemy has two extra kinds of skins: Red and Green. Red skins can burn you, green slow you down. With 1,5x health of enemies you may have problems in rooms where hundreds of frogs or invasion of the bulls. This is not a problem when you have unlimited using F6 (quick save) and F9 (quick load).

Problems and bugs
1. Main problem for me - 1 ammo bag at co-op survival for all players. Its mean if first player will take the ammo bag - the second player will have to wait 30 seconds for respawn of new ammo bag. How play without ammo?! Yes game have places for even 42 players but possible to play only when you play solo at co-op. Even play with 1 friend - you can not play, nothing good will come.
2. Seems for achievement "I am Ugh-Zan" you do not need play all game at this difficulty, run only last level with "I am Ugh-Zan" difficulty, all other levels with tourist is enough. It means that its very easy achievement and anyone can get it without problems. It would be interesting if you need some skills and spend time for training if you are really want this achievement, like "all gold at survivals" TSE HD... Also they changed rules, 2x health were previously. It was much more serious. I am very disappointed, I will not set this achievement for my best.
3. Records at leaderboards.
» Firstly, we can`t check Steam profile of players from the game, we can see only their nicknames with results. Also no any filters for campaign results, just general score for full campaign.
» Secondly, developers did not fair to the players when they deleted many results from leaderboards. Because, now I can see same results which were made with the same scheme. 8+ hours at co-op survival where you can`t pause the game or play with any friends and 1+ hour at "Space ball" map are prove my words. Its obvious for me, why not obvious for developers?!
» Thirdly, no anti-cheat system at game. Still no one red hacked record at leaderboards. This simply can not be after 6 months.
4. During co-op survival match, any players can join to the game. They will not get a result but they can help a lot to the host.
5. Survival mode have 4 maps. "Space ball" have 2x gravity and you do not need to shoot enemies, just walk forward and look at the sky. So only 3 playable maps. I hope that will adds new maps.

LIKED
1. At leaderboards you can see how much kills players got. Its important for survivals... But do not forget that some enemies have friendly fire. Blue golem like a boss. He will help to you a lot.
2. During any kind of co-op games, you can see what damage your teamates and you are gave to enemies... But not restarted after match, cumulative statistics. Need fix.
3. New weapons... But still no hotkeys for them.

OUTPUT
Yes this game have not modern graphics, have many bugs and serious problems which have not completed yet after 6 months,
but cost very cheap and she is made not from Croteam and I got only positive emotions when I played this game. I'm not sorry that I bought it for my collection of Serious Sams. So lets try it too!

I will not give an assessment now since the game is definitely not completed. I hope that will full reset of leaderboards, will adding new content for Survival mode and adding Steam cards.

Good luck Scratch~!

Early Access Review
Well, I put 30 hours Into the game. So, might as well make a review for It finally!


Serious Sam Classics: Revolution Is a game pack.  That reminds me an awful lot of Serious Sam for the Xbox. As It even had The First, and Second Encounters merged Into one big fantastic gore fest.

Now I've been playing Serious Sam since The First Encounter way back, and I haven't stopped playing since then . Sadly I've been living a depressing life, and thanks to Sam he has been there for me, to ease the pain. I'll never regret how much how this game puts me in good spirits even if it's for just short bursts.

Anyways, back to this seriously awesome pack of seriousness. Which like I stated at the start of this review. The first two encounters are included, but now something new is invading the this seriously awesome world. Croteam are implementing a third campaign, which Is still not playable yet. Though since the game Is still In Early Access. Hopefully soon It'll be included. Now I have encountered some bugs and problems with It, but hopefully It'll take notice and Croteam It will get fixed real soon.

Anyways, let's talk about the games contents... shall we?


==[Serious Sam - The First Encounter] ==


So, the game actually doesn't start with much of a story, If you didn't skip the opening credits that Is. The game takes place In Egypt, 3000 B.C. (As Serious Sam states In Serious Sam 3: BFE, a prequel to SS:TFE).

At the start of the game, before the bloodbath really sets in. You get to meet your little AI friend "Netrica". (Or her nickname Nettle, In Serious Sam 2) Though In this review, we'll be calling her Nettie for now. Hehe,She's a AI computer planted Into Sam's brain, and she's Sam's friend, and your guide throughout the experience. Nettle will give you useful tips on things such as the history on the area you're In, Information on the aliens you'll be encountering, etc. She's quite useful, and I recommend reading what she says when you click on your right mouse button.

So, some may say. The point of the game Is just shoot, go to the next arena, and shoot more again. Or kill anything that moves. Nope, It's not only that, but the open areas are beautiful and wide. And there's many secrets to discover In each one If your curious enough to take a treasure hunt. Now for the AI on the monsters, the AI Is just ment to be stupid, really. As the monsters are just pretty mindless, so what's the point of having good AI? Now for the graphics. The graphics were beautiful and fantastic back In 2001. The reflections and many effects the game Is just beautiful. The Serious Engine Is perfectly made, and It was a marvel for It's time."

__________________________


==[Serious Sam - The Second Encounter]==


Alright! Now to move onto Serious Sam: The Second Encounter.


Now, this one Is the cartoons variation of the Serious Sam games. Though that's what I kind of love about the games, the cartoon like vibe and humor! But seriously... Who doesn't?
So, at the ending of Serious Sam: The First Encounter. The Croteam Developers make a rather funny appearance In the opening Intro. Flying flying In rollercoaster like snake of crates, and they accidently smash Into the Sirian UFO that Sam Is In. Sam Is a little enraged by this, and the UFO crashes Into the mountains of South America. Sam thought he'd be In Egypt again, but he was wrong.

Now, as you might now know.  the Serious Sam games have always been known for the Egypt setting. Which I'm pretty sure a lot of gamers got sick of. This was a chance for Croteam to do something else other blast away aliens near towering pyramids. This time however you get some new toys to add to Sams collection. A Sniper Rifle, Flamethrower and Chainsaw. Now, you get to mutilate the invasion with even more "class". Such as the Demons, chainsaw wielding pumpkin heads, and many other deranged baddies. Which just makes the game even more Awesome! Plus your little friend Netrica Is back! And ready to give you more Info!

__________________________


The developers of Serious Sam Classics: Revolution are doing a great job on this! They may need to still work on some bugs, but Croteam is doing a great job altogether though!

And well, that's the end of this review. I wanna thank Croteam for creating this beautifully articulated and well crafted game. Also for this game helping me through the rough times in my life.


I my yellow shades towards you Croteam. For making me the guy I am today . The fact they care even for their work in the past. As this pack makes the originals live long and unformatted. Again, Thank you Croteam, and I hope you'll be making Serious Sam games 'till the day you croak.


Credit goes to ZealousFoX for helping me Improve the review more, and being a great friend.

Early Access Review
Serious Sam Classics: Revolution is a combination of Serious Sam: The First Encounter and Serious Sam: The Second Encounter. The combination of two classic first person shooters not only comes bundled with the two originals, but also with tons of extra features to make it have even more lastability. There are more guns, more modes, and even an extra campaign on the way. (This is an early access review so that hasn't been finished yet) There's also a workshop with lots of interesting custom made levels, full missions, custom scenarios, and tons of changed for textures, skins, and other visuals. There's so much content in this version, along with some controller support and other cool features to better suit newer and broader audiences, that it's practically overflowing!

Beyond all the amazing extra features with this new version, the combination of the two classics into one epic adventure is great. It will be many hours of gameplay shooting down tons of interesting enemies with cool guns in big arena styled combat. Maybe a few minor puzzle bits here and there. And of course, some very large environments to view and explore.

You may not want to get the few changes and additions to the game that are in this version, though. And if not, well this is still an excellent way to get the first two encounters in their original form at the same time! A bit cheaper than the complete pack. You can play them without all the extra stuff added in.

Yet you'll still want Revolution for the workshop content, extra modes, extra campaign, new features, and online capability, though I haven't personally played online. I might in the future, but I'm not too into online stuff, so if anything I'll most likely wait for the full release when more people are buying and playing. Perhaps I'll update this once I've tried it to give you my thoughts on that as well.

So it sure sounds like I'm all for this, but note there are some issues here too. It's early access, so it will be changing still. I'm not sure what will be added, cut, or changed. So it's always risky. Also, the workshop content does seem to be annoying to manage, as you have to delete it from Steam for get rid of it, then boot up the game, have it make the changes, and the reboot it so the changes can be permenent. But it's not too hard to do. There's also the inherent problems with quality control on the workshop, which can compound that pain. Sometimes older items from the original games get put into the workshop but don't work because of the changes in this version, and that can be... frustrating to get in on before others catch it. There's the lack of the new campaign as of now, which... will most likely be coming but isn't really a plus to truly note until it does come. And the biggest thing is... why get this over the HD remakes? Well, it's cheaper, and has different physics... but other than that, it sounds rather comparabile. I don't know much about the HD ones, so I'm unsure if there is a workshop for those or not. This is a fan project that opens up more possibilities than the HD versions do, as far as I can tell. Also, this one actually runs on my computer, so... it's nice for that.

Basically, it comes down to the fact that if you like Serious Sam games, you'll probably love this with all the extended playing you'll get to do. You get this plus the two originals. Three games for the price of ten bucks for one. That's pretty good! And if you already have the originals on Steam... well what the heck are ya waitin' for!? This is FREE for those who already have those! There's no reason to NOT get it then. With all the awesomeness of the originals, the inclusion of them with this purchase, and the incredible amount of extra material even already in the early access version, Serious Sam Classics: Revolution gets an 8/10. Fans of the classic FPS... no need to look in your wallet, you know that 10 bucks is already gone.

Let's call this one the "Definitive Edition" of the Classics, both being fused into one experience while using Steamworks and the Workshop, just like the HD Encounters and BFE does.

Refine the netcode a little, give it a little bit of bugfixing here and there (still getting random crashes occasionally), add the remaining campaign to it and it's good to go.

I've been a fan of SS since it's inception. This is exactly what a fan of this game would want from it. As a Beta, I would hope to see a dead/spectator mode come with release. Also, don't spawn multiply/mutators too many mobs in a small map, though! It'll FPS lag to unplayable mode.

A game worth playing if you like the classic Serious Sam titles or just want something new to play in the series. The graphics stick to being similar if not the same as the classic encounters. The gameplay is the same as the classics with some extra difficulty here and there. Also, a new map is added and two new guns are added(I think). It is not a fantasic revision but it is free if you own the classics already, so it is like a bonus. Also, you have the ability to play Serious Sam: The First Encounter and Serious Sam: The Second Encounter unabridged if you do not wish to switch between games.

If you want the definite version of Serious Sam Classic (The First & Second Encounter) then this is the way to go. It has been updated to better support for modern PC/OS configurations, with improved Widescreen resolution support, with added Achievements and Workshop and various other fixes.

However, if you want the exact same games but with high definition graphics go pick up Serious Sam HD: The First & Second Encounter.
