Unreal is an FPS from 98' that lives up to it's name, one of the most aesthetically pleasing games to date which spawned the fantastic Unreal Tournament 99, which is still hands down the master of arena shooters thanks to Unreals flawless engine, extremely talented mappers and great mechanics.. This is one of those games that you NEED to experience before you kick the bucket as it's pretty much the pinnacle of FPS before the massive decline.
The story is pretty simple, you're an inmate who's prisoner transport ship crash landed on an alien planet and you'll need to explore lengthy, non-linear levels to progress, you can learn some of the games interesting lore by reading messages left on the dead bodies of humans, reading diaries and scripture on walls, similar to that in Metroid Prime where you learn all the lore from scanning objects and alien text on walls.
The graphics are incredible, especially being that it was originally released in 98', which was one of the best years for gaming in my opinion. The sound is superb, the weapons sound deadly and powerful. The atmosphere is relentlessly amazing through-out largely thanks to the sound effects, music, scenery, amazing lighting effects and all round amazingly designed levels which see you exploring large layouts, filled with many paths and many hidden secrets while fighting bad-♥♥♥ enemies that fake their death, dodge your attacks and have different behavioural attributes.
The weapons in Unreal are varied and each behaves in a very unique way, my personal favourite being the Flak Cannon which sends shards of flak at your opponents, shredding them to pieces and has an alternate fire of a grenade that explodes on impact.
I honestly envy you if you haven't played this yet, I'd kill to be able to see everything in this game for the first time again, it's an experience made by true masters who took so many obscure factors into consideration that its scary, this is one solid shooter you don't want to miss out on.
