2027 is a modification and a prequel to Deus Ex 1.
Mod feature full and complete storyline. Much of the gameplay elements you saw in original DX are present here. There are augmentations, items, upgrades etc.
Number of skills is reduced and skills are refactored to be more useful. For example, throwing knives goes to Medicine skill. There are also perks you get based on total number of experience points.
There are items hidden in various places so looking around is recommended. Whole game is surrounded with decent ambient music which adds massively to overall effect.
As always you cant put everything in inventory so creating adequate combination of augs and equipment is essential to be able to handle any situation. You'll need area effect ordnance and defensive capabilities.
Cyborgs in this mod are real tough guys. When you shoot them you hear "clang". All enemies have greater area of detection, especially bots.
There is plenty of lockpicks and multitools around to unlock almost everything, provided you invest at least to Trained rank.
Story mechanics follows up DX. You will have several sides and you must decide whom to join in the end. It'll take you about 10 hours to finish this mod if you are detailed and thourough in you play style.
