Ok I see now. You should be able to empty a 99 round clip by holding down the trigger. Quickly tapping always fires 4 rounds. That almost looks like your mouse is losing connection somehow. Is there any chance you can reconfigure the fire key to something on your keyboard and test it again?

Also this is somewhat related, but can you still run while firing the minigun at your feet?

Yeah I have been having the same issue with firing the weapon. You cant burst fire then immediately go into full auto, your weapon just freezes even if you are holding down your mouse button.

I am on a wired mouse btw.

No, it's not my mouse. I did try it out on another PC.

About the Minigun, yes it seems to be another glitch. Quick demo video of the glitch.

Exactly, you're on the gog release?

I just tested on the Steam version (tap a 4 round burst, then click and hold down the trigger nothing happens) and the same glitch is there. It's one of those things like the minigun run that's been overlooked for years. Certain marine gun such as the pulse rifle do randomly jam, so I just kind of deal with the minor glitch.

Yeah I am on the gog version. I have never played the steam version but outside of multiplayer the gog version seems exactly the same.

I guess we can only hope that the devs become aware of these issues and do something about it (especially the gun freeze bug), but it's not like they have a online bug tracker that you can just report it to.

Another bug introduced to Steam's AvP Classic release is at the end of the Marine episode "Tyrargo" the game immediately crashes to the desktop after going down the last elevator past the praetorian aliens. I'm curious if it's still there.

It's a problem with double-clicking the pulse rifle. Tested it in both the Steam and GOG versions and it's the same result.

About rapid-firing the pistols, I tried the dual-pistols in GOG and am not encountering the same problem as demonstrated in your video. Rapid firing them makes the pistols alternate fire quickly, the same as in Gold Edition.

Don't forget about the mouse aim dead zone added in the steam version.

The behavior in the first video you posted looks the same as the problem I had with my mouse. Your mouse may be failing to register clicks properly. My mouse before I fixed it would often double click, do nothing, release a held click or release and bring it back even though I was still holding the button down.

Try binding fire to your key board.

As for fixing the mouse the problem is an electrical build up on/with in the mouse. You must discharge this some how. Just taking the mouse apart and touching the insides seems to be what does the trick so long as you discharged yourself first. Many people think it is a problem with lubrication or the clicking leaf springs as I did but that is ussually not the problem. Messing with those things discharges the mouse thus people think one of those things was the problem when in was really a static problem. This is a common problem with logitech mice.

Oh and note that the pulse rifle has an overheat feature, it stops firing when overheated. I don't think you can fire all 99 shots in one go. I would have to check but I think it overheats after 40-50 continuous shots.

To fix the mouse aim in steam version (only version I have for windows) I am using this http://homepage.eircom.net/~duncandsl/avp/ which only fixes it while standing. I think the dead zone is also present when using the predator's zoom. Wall running I think is ok.

Beware though that renderer is crash happy.

The pulse rifle, smartgun, and minigun all jam occasionally. The time it occurs is random; I've had it jam immediately upon firing as well as after a long burst of rapid fire.

I also seem to remember that from time to time the pulse rifle would jam, and that it was by design, rather than a bug. Adds to the panic and tension I guess.

So the human race can make space ships, but they forgot how to make proper guns? Of course gameplay doesn't have to be realistic, but this is obviously a bug or an engine oddity.

Yeah, the pistols do normally fire that slowly. Primary fire is more for specific situations where you just need to fire a single precise shot.

There's also a little trick I discovered. If you click primary fire then quickly click and hold secondary fire, you can get the pistols to shoot rapidly one after another. Play around with different timing and you'll see what I mean.

Honestly, though, you're probably best off using the pulse rifle. The pistols are powerful, but they're a little too hard to use effectively.

That said, it can be really fun to try and clear a level with just pistols, and no saves :)

What you're showing in the video is an engine oddity, but the pulse rifle does deliberately jam from time to time.

Well, I've just tested the suggestion about binding fire to a keyboard key and this seems to completely fix the jamming bug you get with having it bound to the mouse. However, there's nothing wrong with the multiple mice that I have tested (just to be on the safe side). This is the only game that I have experienced this annoying thing. The game has issues with the mouse implementation, it's as simple as that really. Now subjectively some people won't notice at all, others will easily notice it. It might be that the game doesn't like a high polling rate of gaming mice, but that's just a theory.

A possible workaround might be to bind fire to the keyboard in-game, but then bind 'mouse1' to the same keyboard key as it set to 'fire'. You can do this with special software. I don't know if I'll bother to test this out, but the result would be interesting. If the game has had mouse issues since launch then it'll probably never be fixed.

Yes, the pistol does fire more slowly than full auto, but I can still fire much faster by having 'fire' bound to the keyboard with the pistol. It makes sense when the game doesn't register half the mouse inputs. When the Pulse Rifle jams (per intention) there's a sound played, yes? That's something to look for when comparing the 'jam bug' with the 'deliberately jam'.

Oh, that is odd.

Seems I learn something new about AvP every time I talk about it :P.
