Steam's new feature allows game publishers to release access to the game free for a limited time. Unlike the demo, the free game trial allows players to enjoy the full game features for 90 minutes, which also allows players to test run the game to see whether their PC could handle it or not.
Keep in mind that after 90 minutes are up, players will have to buy the full game to continue playing. With that being said, the Dead Space Remake is currently having a 20% off on Steam for RM159.20 (ori RM199), the offer will end on 30 May. It's about time to check out the third-person sci-fi horror shooter on Steam now if you haven't.
