About this sound

This is a short voice line from a Half-Life scientist, delivered in a hesitant, uncertain tone as he admits he is not at all sure. It lasts just over a second, with the scientist's flat, nervous delivery making the doubt feel awkward and funny. It works as a quick, deadpan reply when confidence would sound wrong, giving a small moment of comic hesitation.

Pro tip

Use it as the whole reply, with nothing before or after it. The uncertainty is the joke, so letting that answer stand alone makes the doubt feel sharper and funnier.

Good to know

Place it right after a question is asked in the edit, so the reply lands as the answer. Follow it with Nope for a firmer refusal, or put Enemy Spotted before it when a teammate spots trouble and still has no plan.

FAQ

Can I save the Not At All Sure clip as a ringtone on my phone?

Yes, save the MP3 to your phone and set it as a ringtone or notification tone in your sound settings. It is easy to recognise as a quick alert.

What should I pair with the Not At All Sure clip in a gaming edit?

Pair it with a question clip first, then a firm refusal or a confused reaction afterwards. That order turns one uncertain answer into a short exchange that feels like a real conversation.

Is the Not At All Sure clip good for replying in a group chat?

Yes, it works best as a single short reply when someone asks a question nobody in the group can answer. It reads as honest and funny without needing any extra explanation.
