This is - incredible, @pahammond.

I will state that the voices in the original BERZERK would change pitch. I especially remember these two sentences together when you were shot, they were almost SANG out.

"Got the humanoid." -- low pitch
"Got the intruder." -- medium pitch

And when Otto appeared:

"Intruder alert. Intruder alert." -- low pitch

In most cases the voices would repeat the words but at different pitches.


Here you can hear it almost singing those two sentences above as the player is shot.


Also when the player is hit he has this cool kind of rainbow effect appear around him as if he is dematerializing. I think this can be done in Pico-8.

@pahammond, this is terrific. Congratulations! One favor, though, can you change the credit for Speako8 to just @bikibird? I prefer to go just by my screen name in most places. Thanks.

@pahammond. Great game - lots of fun especially when you get the 8 way fire.

There is a bug that if you keep going left, when the room "x" position goes less than 1, the player is killed instantly when entering the room and then restarts as if they had entered the room from the left door.

Also did you update the game so that you no longer score when a robot dies by any means? I'm sure that when I first played this, my score increased when a robot dies regardless of how it died...

P#118057 2022-09-27 16:10

@bikibird. No problem, I’ll update it later today. My apologies, I should have checked.

P#118063 2022-09-27 17:33

@phil. Damn, that’s the only bug my tester picked up and I thought I’d fixed it. Only happened on the vertical before though. I’ll fix it tonight.

And no, I only ever award a score if the player bullet hits a robot.

P#118064 2022-09-27 17:36

Nice game!
Is there any goal of this game aside of scoring? or just survive as long as you can?

P#118101 2022-09-28 05:34

@Bloodbane. You got it, just survive as long as you can! Old school!

P#118103 2022-09-28 08:44

Love this game!

P#118107 2022-09-28 13:00 ( Edited 2022-09-28 13:00)

@bikibird. All updated, including my page on itch.io.

Hopefully I'll get to use speako8 again, it adds a new dimension!

P#118123 2022-09-28 18:47

Cool! Looking forward to that!

P#118127 2022-09-28 19:17

Cool remake! I couldn't imagine a better occasion to use Speako8
(best: 5100)

P#118337 2022-10-01 23:04 ( Edited 2022-10-01 23:40)

pretty authentic.
score: 3650

P#119468 2022-10-23 05:22

Fantastic implementation. This is what pico8 is all about!

P#119613 2022-10-26 17:38

Every time I leave a room there's a fraction in the lower right corner, like 17/21 or 16/20. What does it mean? By best score so far is 6750.

P#119637 2022-10-27 01:35 ( Edited 2022-10-27 01:36)

@pavo6503 the fraction is actually the room number. Rooms are in a 256x256 grid so 14/16 would mean (counting from the top-left) that you're 14 in and 16 rooms down.

Means you can rediscover interesting room. Otherwise you can just ignore it.

P#119638 2022-10-27 01:46

@pahammond Thanks, I had a feeling it was something like that. Very nice job on the game, it's been my go-to time killer for the past week

Really impressive use of speech on Pico-8 and a great remake.

I made a video for my channel here:

Would like to add this if possible, @pahammond:

If you hold the fire button but are not holding down the direction arrow, you still continue to fire in the last direction you fired (auto-fire). No need to hold down the arrow key.
