After the "Assault on Roswell" you destroyed the Alien Virus. at least you think you did !, it seems you yourself were infected and have become a carrier of this mind altering disease and are the unwilling host bringing the virus to your place of birth Portown...
Assault On Roswell was a classic mod (to me), And it always will be. When Riot In Progress was made.. Many were less than happy with it. Me? It's an ok mod but it can become a hassle.
The main thing was that using Save when you don't have any of the save icons will hurt you (this has been fixed since i played it a while back)
Riot In Progress gives you a large arsenal of weapons to use against enemies, Thought there are no cheats.. It is not impossible to survive.
The mapping is very solid and it feels like a genuine Half-Life mod because of the atmosphere. At times, It may seem like it is impossible to go any further but likely you are not looking around enough.
Nice mod with a lot of effort put into it. I rated it a 5 because two intentional, non-bug features ended up frustrating me enough that I never finished playing the mod.
One is the save gem system. It's bad, but maybe not the worst thing in the world. A little bit of strategy in using save gems takes out a lot of the difficulty these add. Still, they artificially extend how long the mod takes to complete because missing jumps, getting shot by an enemy you missed, etc. means you often get set back pretty far. Also, to use any strategy in spacing out saves means you'll have to start the game over a bunch of times.
The other was the security-camera view that's used in a lot of sections of the game. Half-Life's control scheme wasn't intended for this sort of camera, it just wasn't. This feature feels like a trick that the developer figured out, thought was cool, and decided to put everywhere without realizing what an incredible pain in the *** it is in actual gameplay. Now, normally, this would only be an annoyance, as it's only used in some sections, but combined with the save gem system, it becomes an unforgiving mechanic that artificially inflates difficulty for no good reason, and sets you back ten minutes or more because it is invariably easier to die in these sections than in others.
All in all, the mod is worth a download and a try, but the fact that the developer takes cues from Daikatana should be enough to suggest that it's not really worth it to stick around until the credits roll.
