Missile Commandeer Game (including Source)

First XNA game...done! It's an old school missile commander clone (only its CommandeEr, like pirates...ARRRR!!!). I spent extra time to maintain the original "cutting edge" graphics to make it atrueclassic. Check it out...

(I just added the screenshots, game and source code to my website)

Click here for the game

Improvements to come:

- MIRV missiles

- Extra lives

- High scores

- suggestions?

Very nice. This is the first XNA game that was really fun for me to

play (Not that I've tried many). I really enjoyed the classic feel.

Definitely worth the download.

As for suggestions go, maybe you should display the level/wave no. the player is currently on.

This is really picky, and definitely not a major issue, but is would be

nice if the splash screen texture did not get fuzzy round the edges

when it is enlarged to retain the classic feel. As i said, not

important :)

I did notice that the game gets stuck if you carry on firing missiles

for a while after a level is finished. It doesn't change the score and

just waits on an empty (no enemies) screen.

Also, on my computer if I fire 3 missiles in quick succession, one of

them won't explode, the blue trail will just disappear as it reaches

its end point.

Anyway, as i said, this game is really cool.

My top score so far is 6265 :)

Good work man!

Very fun. I think I encountered the same issue with the missiles, but can't confirm since I was using my peripheral vision and didn't see what happened.

Should points really be taken off if a destroyed city is hit again? It's not destroying anything, right?

10890 first time out.

Thanks a lot for taking the time to do this, I (and the community) really appreciate you sharing the source code and making this great resource available.

Nice job and keep up the great work!

Nice update, I especially like the MIRVs.

I haven't played it much but my top score is 16440 on level 18. I'm pretty sure that other people have done way better :)

I think the score penalty for hitting destroyed cities should be raised again. The problem that I
found was that even without much skill you can quite easily defend your last city especially if its
next to the cannon, this means its easy to play for a long time without dying or losing score(As you did in the previous version). I preferred the faster arcade action that could only last for a few minutes unless you were really, really good (like Jim Perry ;).

The reason I died that time was because I accidentally clicked on my desktop when trying to shoot at a missile going towards an edge city, it would be nice to be able to toggle to fullscreen mode.

I like the other improvements you've made though, I hope to get a chance to look at your code soon when I'm not so busy.

Thanks for making this available. Great stuff :)

Well done, this is really quite adictive

One small comment, I was a bit of a dab hand on the original arcade version and the key was using the explosion to hit several missiles at one time. It would be good if you could make the explosion last a bit longer so that you could time your fire to destroy multiple warheads in one go.

Keep up the good work !.

Very nice! Thought I would just take a look at the source... ended up playing it for a half hour.

Well done and thanks.

Very fun. Managed a little over 10K in the quick game I played. That was using a touchpad on my laptop so I can probably do better.

JimPerry at 2007-9-4 >
