If you have not played Silent Storm and expansion Sentinels, you are in for a treat. GOG.com (Good Old Games) has finally restored one of the best overlooked games of all time. A game Nival pretty much neglected after a couple of years. After a few years SS was unplayable on most newer machines and video cards. GOG has remedied this and added SS Gold to the catalog.
If you are a fan of XCOM, Jagged Alliance and TBS in general, this is a must play. Even if you just want to try something now. The amazing engine holds up quite well even today. A revived Jagged Alliance game was supposed to use this engine but the developer abandoned it or went belly up or something.
I highly recommend this game and to top it off GOG has SS Gold on sale for $4 bucks right now.
