Sierra 7
This walkthrough is a breakdown of tips for each level.
General Tips

Remember to check your bullets. The best time is when the game pauses in front of a door and you have to press [space] to proceed. Reload then. But be vigilant - you have limited ammo clips and any bullets you don't use before a reload you lose.

Playing on low quality will improve the speed of the game, so remember to tone it down (in the Options menu).

You can only change difficulties before you start and after you finish the game. If you change the difficulty after finishing the game, you will lose all the mission-specific emblems, but keep the general ones (such as 25 Pistol Kills).

If you need to sharpen your skills (or just be challenged further), play the challenges.

If you step into a scene and don't move on within two or so seconds, it means you will be attacked soon.

Unlocks

Medkit:

Beat a level with 100% health.

Vest Tier:

Finish a mission without reloading. This gives you two extra clips.

Springfield Operator handgun:

Get 25 kills.

H&K G36C:

Kill everyone on the sniper level without missing.

Colt M4A1 Socom:

Get 50 headshots.

H&K USP:

Get 50 pistol kills.

H&K MK23:

Get 25 suppressed kills (use the Colt M4A1 Socom).

Benelli M4 Super:

Finish game on Recruit difficulty.

M60 7.26 Nato:

Finish fame on Veteren (sic) difficulty.

Levels

Training

The enemy patterns are always the same.

Set your gun to Semi (tap [f] until you see 'Semi' on the HUD next to your bullet count.

Irish Safehouse

This is a good level to get the 100% health and No Reloads emblems. Use a shotgun to do the 100% health run.

Completing this level unlocks the Mossberg 590 Tactical 126 shotgun.

A shotgun is the best weapon for this level.

Tangiers Hotel

Completing this mission unlocks the Bomb Diffusion emblem.

A pistol is the best weapon for this mission.

Completing this level unlocks the Colt M4A1 5.56 assault rifle.

RSA Embassy

Unlocks the AK-47.

Unlocks the Helicopter Insertion emblem.

There are two guys at the end who will execute the hostages. You have to shoot both before they do. A pistol is the best weapon of the job.

Kosovo Sniping

If you tap [space] while looking down the scope, you will zoom in more.

Watch the wind. Aim on the opposite side of which the flag is showing. So if the flag is blowing right, aim to the left of your target.

Getting the 100% accuracy emblem unlocks the H&K G36C.

Kosovo Base

This level features a lot of people popping out of cover. Keep an eye out for long pauses - it means an attack is imminent.

At the end you have to stop the commander from committing suicide. Use a pistol and shoot at his arm.

Somalia Street

Building

At the wall you can peek out. Keep your head out and shoot at the soldiers appearing in the windows and only move to cover when you reload.

Armed truck

The trick to beating the truck is to get your cursor in place. Peek over the cover and move the cursor towards the guy in the back of the truck. Remember to duck down behind cover before he starts shooting again. If you don't move the mouse when going back to cover - and come out of cover again - the cursor will point to where you aimed it the last time you peeked. Line up the cursor and then take pot-shots between the salvos.

Use Burst Mode [f] to get short bursts in when you fire back.

If you let go of [space], you will start going back to cover. Use this to peek out and start shooting as you duck back.

The first salvo is a burst of about five shots. It's easy to distinguish the gaps.

The second salvo are two bursts, around 3 then 4 shots each. Wait for both bursts before shooting back.

The third salvo is tricky - two bursts of three bullets each. The gap to shoot back is just slightly longer than between the bursts.

Thanks to James Francis for the walkthrough!

The Kongregate badges recently appeared for this game, and they include completing the challenges. I didn't see a walkthrough online anywhere, so I figure I'd post one here.

Challenges walkthrough (particularly for the Kongregate challenge badge):

Sniper Field:

* You must have 100% accuracy and finish within 60 seconds for 70k points.
* Don't bother zooming in twice for most shots. (wastes time)
* After you shoot, you have 1 second to line up your next shot (in the 1st zoom level). This saves the most time by far.
* A little obvious, but if you're no good with wind adjusting, go after far targets when there's no wind. Save you closer targets for when you have wind.

Pistol Room:

* Memorize the placement and when to reload. You need to be reloading before the text comes up.
* In order to get 50k points, you either need to hit all 43 targets and miss up to 16 times or so, or hit 42 targets with 100% accuracy (not shooting and missing at 1 target). People who are bad at timing that last fast moving target in the second set may want to just ignore shooting at it completely if you can get 100% on the other 42.

Hostile Arena (scoring seems buggy):

* First: The level seems buggy. The challenge ends after 5 waves instead of 6, holding down space while you're in the game skips over the summary screen, I didn't get credit for headshots, at one point I had 200% accuracy, etc.
* To get 10k: Just get 100% accuracy then die. IE: Switch to semi fire or pistol and shoot someone once.
* IF it weren't buggy, I'd recommend: Getting pills (beat a mission at 100% life) and use the m60 for its high damage and no need to reload (aim for head, but most anything else will kill)

Gun Running:

* Complete the game in the easiest recruit level and use that shotgun (the best shotgun). It enables quick shots and fast reload and will score you a very high accuracy. With a shotgun, this challenge is significantly easier.
* Don't forget you can shoot through the corners of the wall if the targets have just passed.

Long Range:

* I liked the M4A1 for accuracy, AK47 didn't seem to cut it. The last pistol also works, but requires more reloading.
* Switch to Semi-automatic fire.
* You can shoot the targets through pretty much any cover.
* For 60k points aim for a 90% accuracy in under a minute. Take your time, each missed bullet costs you about 4 seconds. In comparison, at 80% accuracy you'd need to finish in 40 seconds (nearly impossible).

Other thoughts:
I really like the way this game does 3D elements! I haven't seen much like this without plugins in a flash game, it's pretty impressive. (wait, it's not a Unity game, right?)
To change difficulty, just beat the last mission again. You won't lose most weapons or badges that are not related to beating specific missions.

This game is fun as anything, but the sniping mission is so annoying! Trying to connect with my inner Golgo 13 is harder than I thought.

This game is really enjoyable! I absolutely love arcade rail shooters (House of the Dead, anyone? How about Time Crisis?) and this is really well executed. I had to take a step back when I got to the level where you need to peak out from behind cover with guys constantly shooting at you, but I will definitely be back to finish the game. Definitely a solidly put together game in my opinion!

Anyone else not gotten the "shoot 50 targets" badge despite having shot at least 50 targets? Does it have to be 50 targets in one round?

Having trouble with the "Time Crisis" section of the last mission. Whenever I hold the space bar down, mouse movement has no effect on the aiming reticule.

Kind of a shame, because the game's been a lot of fun up to that point.

@Nimdok - I also was confused over this achievement.

They're not referring to the targets in the Challenge levels, but rather the targets in the training level. A little annoying because you'll need to replay that level at least twice to get the badge, but a relief once you figure it out if you're a completionist like me.

Is there any way to change difficulty without erasing all data? I want to try harder modes but I don't want to lose all my unlocks and emblems. Especially the 100% sniping that I got first time and don't think I could repeat.

Weird, I found the sniping part easy. I got the first 4 guards like it was second nature on the 1st try but wasted 5 shots on the inspector. I got all of them the next time!

Also, it's fun to not wear the night vision goggles and claim goggles are for sissies, real men use their eyes.

I found hard mode disappointing. The only change I noticed was that enemies deal more damage and taking pills heals less. Other than that, great game but a little short.

I loved this game. The thing I'm having a problem with is the silent kills emblem. How do you do that?

I enjoy it a lot, except for the challenge mission and the final mission, when you have to hide behind cover and shoot. In each instance I hold down the space bar and move the mouse, but the cursor on screen doesn't move, and pressing the mouse button doesn't fire. That's quite game-breaking for that to happen on the final mission.

for the sequel i think he should have more sniping sections with moving targets i found it a lot of fun! on the cover based sections, i my frame rate sometimes dips drastically (maybe fix that) finally, i think for the next game maybe give us the ability to use grenades or flash bangs to disorient the enemy on those hostage sections. really good game play it!

best flash FPS (it is even a rail one!) in history on Earth. Hands down.

Btw, you can't really suggest or hope about what they are going to have in the sequel, we don't even know if this developer is planning to do it. In my opinion, he should make an entirely new game, doesn't even have to be fps, but a shooter would be nice.



A few little things I would like are melee attack, throwing knifes(dart), and grenade. Also, I really like the idea of shooting while running (the run and gun challenge) and it should be incorporated into the campaign missions. Or even make Sierra jump shoot and roll.



It would be awesome if we could have a game with Metal Gear Solid materials, spying upon on enemies (this is where melee weapon is crucial)

sorry for double post but
@Jimmothy

silent kill is when you 1 shot ( headshot) an enemy without making them groan or make any sound that alerts other enemies. You can do this with any weapon, don't listen to the one above me.
I found pistols to be better at this task
