Alfons: you are playing the v6 beta, not the latest version in need of testing. Sending the update.
Sneaking: Sneaking gets harder as the game progresses. Firstly because there is a lot of close quarters level design later on, and secondly because augmented enemies have better vision and stats all round than standard. This in addition to cameras & turrets being a major threat.
Assault Rifle: Whilst I agree with you that the weapon's five round burst is silly, it's still a extremely useful weapon, especially after it's modifications, and the ammo amount is just right. I've reduced a lot of the ammo you find in the game, only the prod & the assault gun are somewhat of an exception. So whilst you don't get a ton of Assault gun ammo vanilla, it works out fine for GMDX.
Since you do not have the latest version of GMDX you are missing some new features of this weapon.
Laser mod: Yeah it gives you perfect accuracy, same as vanilla. It's Shifter that adds the sway to it, which people
didn't seem to enjoy. Myself I dislike Shifter's approach because it automatically turns on the laser. Automated gameplay is a big no-no for me. Laser may give you perfect accuracy, but the mod is rare and it's downside is you have to remember to turn it on first.
You're missing features of the laser because you don't have the latest version also. New toggle on/off SFX, and the blob size increased further still so you can see it even further away.
Another thing, I hadn't touched the mod in about a week until today. I recompiled the code just for one thing: to fix the Mini-xbow fire sound bug (you'll notice when shooting it has the same SFX as the stealth pistol vanilla). A very minor thing but it's just one more modification that makes the mini-xbow even more badass. This will feature in the public release of v6.1, so it's not in your test package unfortunately. It's an extremely minor thing in the mods scope though.
I'm not sure why I felt like sharing that, I think I've developed an attachment to the Xbow, which I wasn't even much a fan of in the vanilla game
Puns intended.
Anyway, I'm looking for more testers, & thanks to the current participants. You won't see GMDX's true colours until you play the game in it's entirety. A lot of modifications are on a per map basis, and of course it depends on what build you went for too.
