I bought it yesterday, even though all my senses were telling me not to.
When a game is released without any publicity and before any reviews are published, it often means that they are trying to shift a few copies before anyone can spread word about how bad it is. I prayed that this was not the case with "The Regiment" as it sounded like such a good idea.
Here is my first impressions of the game -
Concept - Excellent, like SWAT 4 but full on. "When the SAS go in, all negotiations have ceased"
Gameplay - Due to a mixture of technical problems and difficult, almost fussy gameplay I didn't even manage to finish the Room clearing training missions. These training missions give you simple tasks to complete and then require you to do them in a ridiculously short amount of time, so you have to rush around like a lunatic. I know the SAS are supremely well trained, fit and tough but I doubt even they can enter, dominate and clear three rooms in thirteen seconds, having got 100% accuracy at hitting the numerous training targets along the way. Nope, the training missions are not great.
Anyway, after my twentieth failed attempt at the fourth training mission (And second sudden reboot), I though I would have a go at the first mission (You have to complete this before you can go on to the next one), The Iranian Embassy Siege. Went through the pre mission briefing, only for the thing to crash out to desktop before it started. Did this a few times, so I decided to try the multiplayer. I selected the internet option to be greeted with all of six servers available. Chose one and it started to connect, only then to dump out to desktop. Tried again, connecting to another server and this time I managed to join a co-op game. Brilliant, managed to play for two minutes (Killed a couple of terrorists) and was just starting to think that maybe I hadn't wasted my money after all, when my PC rebooted.
Summary - Good idea, but massively unstable, even with the patch that was available on day of release. From what I have managed to play between crashes and reboots, the training mssions seem to be pointlessly hard for all the wrong reasons. Can't comment on actual single player gameplay and didn't really get enough of a taste of multplayer to make a judgement.
Prognosis does not look good, shame about that.
