Half-Life Before is such a weird situation. The level itself is fine enough but that is kinda the only thing saving it. The enemies feel randomly scattered and don't seem like they were actually placed in good spots. The gimmick of having to push boxes to get to certain points isn't the worst thing ever but it feels so slow and seems like an excuse for a "puzzle." The boss fight is terrible and what makes it worse is that if you let go of your walk button for even a second, you are going to die and you'll have to rewatch the cutscene over and over until you stop dying and beat the boss. It isn't hard, but having to keep walking backwards while shooting, hoping to not bump into any walls is really tedious. Overall the game is a mess with like very few redeemable qualities. It can be beat in less than like 4 minutes so you might as well play it for yourself. Just don't expect anything good.
