Found another bug.  The "mute" setting isn't checked when Zombies devour civilians.  So you'll quietly be playing when all of a sudden a Zombie gets thru your defenses and blood curdling screams start blasting out your speakers.. at work.  

Zombie Test #6.  Graphics have been changed to ones that I could find with multiple types of soldier unit.  Unfortunately these ones don't rotate.  All I'll be able to do (which I'm not doing yet) is flip them to face the opposite direction when Zombies get past them.

So now I've included a bunch of different units.  (My fav is the Flame Thrower!)  Bazooka unit still needs work, as he's supposed to have a huge area of damage when those shells explode.  So I wouldn't recommend spending money on him yet.

Barriers currently all behave the same, so don't expect any benefit from buying Brick Wall vs Boxes.

Zombies actually run from fire!  Eventually they'll build up the courage to have another go at it though.

Fixed the non-mutable civilian screams.  But Flame Thrower and Bazooka need updated sound effects.

Let me know if you find any other problems.

Your scoring needs work.  As I was at 3 Billion points, then sudden jumped back to 800,000,000!  What a rip off! .

I've found your men shoot from their mouths not from the end of their guns.

For bazooka I had no problems, but there shouldn't be a delay for the explosion.

Other than that I enjoyed playing it.  At one time during the unbeleivable level I had lost all my heros and suddenly the zombies broke through.  I un-muted as all 100 of my people were eaten... made for quite a stiring symphony.

Shooting from their mouths is visually unappealing, yes.  That can be fixed.

Interesting about the Bazooka:  You don't like the explosion delay, but Shabadu does.

Unless you were going for projectile vomit bullets, yeah out of the gun would be cooler.

Also are you looking to change the size, looks of the zombies.. so that people visually can see that the tougher zombies are coming

The intent is to have multiple different types of enemies, not just the same old Zombie character every round (as satisfying as mowing them down with a line of machine guns is).  It's just the only enemy graphic I've found useful off the web thus far.  Plus, I'm still working on game mechanics, so I'd rather get everything right for the Zombie first.  (Rather than loading up on different enemy types and having to go and adjust every one of them for each change)

I think you're aware already that heroes respawn each night.. but often after they die the zombies do al ittle dance.. eat a little flesh and stay on the spot where your hero was last seen alive, essentially freezing the game because the wave never ends.. most frustrating as the only solution is to restart the whole thing!

Also, I'm thinking you may need to tweak the reward for killing zombies... I felt before you got waaay too much, but now I think you get a little too little.  Or perhaps your cheapest hero should just be cheaper?  

Oh also.. bullets should not be slower than zombies.. too many times my bullets are chasing zombies who have already passed my hero while others chew him to death.. and the bullets cannot catch zombies once they have passed the hero.. it that is the case then heroes shouldn't shoot backwards.. or more aptly their bullets should be able to strike the zombies so their deaths are not COMPLETELY in vain...

Fixed forever Zombie dancing on Hero graves.
Fixed Heroes respawning next level if they die.
Fixed barrier behaviour.  Now only Walls block.  Others slow to various degrees.
A couple other behind the scenes changes (for when we get more enemies than just Zombies)
It also seems a heck of a lot tougher now!

There will be another version on Sunday, I'm sure.  But for tonight, I have a few surprises beyond the "Unbelievable" level.  This may be your best opportunity to see it before I balance the game again and make it harder.
Tomorrows changes will involve performance.  I've recently added animation to all the enemies, however it really drags the FPS down while loading new sprites.  I think I know how to fix that though.  Hence the version coming tomorrow.

As expected, I posted a new version of the Zombie game late Sunday night.  We're at revision 19 now.
It's balanced to make it somewhat easier to make it to the end, but not to get past that.  (I'm sure someone will find a way, but I haven't yet).  The animation doesn't slow down the game any more, and the final characters do shoot back.
If you haven't tried it yet, you should!

Shabadu wanted me to post his screenshot of acheivement.  I'm impressed with how well he did, but the level still has yet to be beat.

You still need to change things so that heros will target enemies closest to them, or are actively gnawing on their necks.

Targeting will be a tougher one to fix, but I agree, it should be done.  Including "predicting" where the Zombie will be by the time the bullet gets there.
Tonight was just a quick change.  A coworker found that a lot of flamethrowers will slow the game to a crawl, so I've fixed that.  I've also added a new unit for you to aspire to acquire.  Basically you'll have to get through the game before you can afford one (which can be done!).
Added some more sounds.  I felt cat deaths really require some kitty squeals.  

Only 7 dead and I got a tank! -what can you wee boys do?
