About Lost Prototype

Lost Prototype is a ‘game’ created by an unnamed developer.You are asked to try this game...or ‘prototype’ and find a way out.Something is hiding in this prototype or someone,  we don't know.Just avoid getting caught. This game lasts about 10 to 20 minutes and contains flashing lights and sometimes loud noises.(Lost Prototype is a test ‘game’ to train myself on Unreal Engine and especially to make my steamwork account and stuff).

Well, it's free so why not? The game does what it sets out to do... It's exactly as described. Pretty sweet for a first game, IMO. I can totally imagine this as part of a larger project - this being just 1 of 20 levels, or the tutorial, for example. I wish the developer good luck!😊

If you don't like navigating a maze while a lame monster chases you while intentional glitches randomly mess with you, then avoid this game. If by some chance that happens to be your thing, have at it. Yeah, I know, that's the whole point of the game, but it frustrated me enough that I didn't even finish the game. Maybe there was some critical game mechanic that I missed somehow, but I don't think so. I don't want to be too harsh here, the game plays perfectly well, and looks o.k. too, but the teleporters and lack of any kind of direction or map made this game just too frustrating. Sort of sad "no, ty" on this one.

I don't know why but How to Play section commentary made me laugh a little. I hope the dev makes more game in the future!

Wander around mostly empty rooms, get caught by an entity, boring and pointless.
