Been a while ! https://store.steampowered.com/app/43110/ Edit : This is the original btw, not the Redux
8 year old game and they only make it free for a day instead of get it free permanently within next 24h
Some people say free once you claim it, others say its yours permanently if you download it before the time is up, not sure what to believe at this point, they should word it better.
If the other limited time freebies (like Orwell earlier this month, not weekend trials with countdowns) are anything to go by, it’ll stay in your account once you click that “play” button. Either way, do it anyway, and then be pleasantly suprised that it’s there a month later, while you’re looking at your backlog of games that you haven’t touched.
You only need to claim it in 24 hours and you will keep it forever, giving away old games for free like this is already usual stuff on Steam
