LD50 Version 1.2 has been submitted to Apple.  The very brief release notes:

Added local head-to-head mode: 2 players can now play against each other on the same device!

That's right... local multiplayer... which means two human players on the same iPhone/iPod touch.  Network multiplayer is being investigated for release with iPhone OS 3.0.

Also, the team at 148Apps.com was nice enough to do a review of LD50:


Version 1.1 of LD50 is pending Apple's approval right now. It was submitted on Thursday the 19th, so I expect it to pop on the 24th or 25th. LD50 Lite was submitted about 12 hours after LD50, so it should be on a similar schedule.

The brief release notes:

Improved rendering performance.
Improved user-interface interactivity.
Improved computer opponent AI.
Added starry skybox.
Changed computer opponent animation.
Rebalanced weapons.
Various minor bug fixes.

The ad hoc version for ibetatest.com beta testers is in the usual place.

Version 1.2 is under development and should follow in a week or so. Stay tuned to find out what's new in 1.2!

The game features lush, deformable terrain; exciting 3D graphics and effects; a range of highly explosive weapons; and multiple gameplay modes against a challenging computer opponent. Developed from the ground up for the iPhone and iPod touch, the game has an intuitive and visually appealing touch interface and uses the built-in accelerometer for control of a few of the most devastating weapons.

LD50 Gear

March 9th, 2009

Sure... why not... it's time for some LD50 t-shirts and other gear:

buy unique gifts at Zazzle

Woot. Here's the iTunes link which will work from the device or a desktop computer:


I encourage you to grab a copy and leave a [super awesome] review.

I had to resubmit LD50 Lite because I was too shameless in my upsell to LD50.  It should be out in 5-7 days.

Thanks for your support!

BTW, if you were a member of the beta program, I'll be sending out an update on how to get a copy shortly.

LD50 Web Site Beta is Up

Version 1.0 Release Notes

March 2nd, 2009

Issues addressed in v 1.0:

  • AI now gives priority to the use of defensive maneuvers, esp. shield, to prolong battles.
  • Fixed crash on startup when going from splash screen to new game.
  • Fixed memory leak in 3D file loading.  No remaining memory leaks.
  • Fixed issue where purchases in store might not be credited to player.
  • Fixed issue where help pops up on resume when player is out of ammo.
  • Changed guided missile accelerometer input scaling in low  and medium difficulty.
  • Fixed issue where computer did not do the right number of shot probes when switching difficulty.
  • Moderately fixed issue where computer does not intelligently recover from a low shot that continually misses.
  • Improved issue where strategically placed earthquake trail can leave player hovering in mid air.
  • Improved level loading time by as much as 50% !!!
  • Changed crash handling.  If the game crashes (never!) it will restart with the last state.  If it crashes again immediately, it will restart and ignore any saved state.  All progress will be lost but at least game will run again.
  • New application icon looks much less like a push-pin.

Wrapping Up

February 27th, 2009

Well... it's getting close. I have a little more tuning and testing to do and then I'll submit LD50 to Apple.

Two things to note:

1) I've been meaning to come up with a new app icon. I like the current one... but a few folks have said it just looks like a push-pin to them. So, here's a contact sheet of possible new icons. Check them out and then fill out this form to let me know which one you like.

2) I'd like to get a little bit of closure on the beta test, so I've put together a quick questionnaire that I'd like testers to fill out. The questionnaire is here... please go poke some values into it.
