Hehe- well let me try to address your concerns.. not that I will convince you to change your mind or anything-
The frag grenade has a 5 second fuze.. this does seem like a long time in the middle of a battle, but these battles aren't yet very realistic. As far as grenade throwing goes, I guess that will always be classed as an opinion thing since I feel it's fairly good. I should point out that I'm fairly biased though.. /infopop/emoticons/icon_smile.gif
The whole concept of the weapons needing to be loaded first stems from another part of reality-- you wouldn't find a gun just sitting on the ground 'ready to fire'. First of all, they would be grouped together somehow, or at least put in places other than the floor. Technically, the only place you should pick a weapon off the floor is from the fingers of a cold, dead bot/player- in which case you won't need to perform the initial load anyhow. Second, it's just plain fake to have a not-yet-used weapon with a bullet already in the chamber unless someone went around and charged the bolt on every weapon before gameplay. This is perhaps one of the most realistic parts of the weapons. The only guns that don't do this is the shotgun (which works kinda differently anyhow), the HK69 (the reloading sequence takes too long in this case), and the PSG1 sniper rifle (because I didn't finish the weapon in time). The PSG1 will work similiar to the other weapons, but the Robar won't since it's a bolt action rifle. So to sum that part up, it's just plain wrong to pick up a new weapon and expect it to fire when you pull the trigger.
The StandOff speed is limited in general. Our concept of StandOff is to eventually be as realistic as possible. The default speed of this is like walking. It would be nice if you could say hold down Shift and have a burst of running, but it would make more noise and be harder to shoot your weapon accurately. Unfortunately though, this isn't possible yet because Unreal has 2 speeds- running and walking-- and the default speed is running.. so if that is already slow, you can't go anywhere but down.. At this time, with the whole concept of StandOff being realism, we'll keep the speed the same and consider it the more strategic game mode. I personally love it.
We will be adding ballistics to the weapons in version 3, but adding barrel heat and bullet cook-off temps will have to take a back burner. The gun 'lifting up' is to force the player to compensate for kick in a weapon, of course. The M16 is very good at this too. In our opinion, we consider the player already knows how to use all these weapons and thus holding down the trigger on an automatic weapon won't decrease your accuracy a whole lot. The idea is to allow the player more control of how 'bad' he/she shoots. As the course of Infiltration progresses, we'll fine-tune this as best we can to make it the most realistic.
Hope that gave you a general idea of the how and why- but don't hesitate to post your opinions because sometimes we see ones that will make it into a future version! You should see my Infiltration Ideas txt file!
