Done with act 3. Another lame boss (found a spot of invulnerability in the building that let me heal as much as I wanted) and somehow a worse backstory than the laughing boss. I was cringing at the dialouge/story/voice in this whole sequence. Talk about terrible. What's great is that some scenes are very well done and yet you have these 2 that are utter shit and if you found this in any other game, it'd be a laughing stock.
Yeah, I know which spot you're refering to. I was hiding under the staircase desparately during that fight because I only had 1 ration left before the boss fight started. I wouldn't have made it without that spot. I think there are more than 1 location for quick health recovery though.
For most boss fights in MGS4, there is always an easy way out (for noobs like me).
If you have enough health, you can also go up the building and enjoy the rooftop view of the city. The building will be torn apart slowly (scripted) like in the lower floor. You will also find out what Raging Raven is doing when you take cover. ;-)
I like Act 3 because the resistance member tracking and the bike chase stages gave more variety to the game. I also love the art direction there.
Once they discover you, they should surely act like good AI found on FPS! Instead, you can easily pick a choke point, shit there and head shot away until they stop coming. How about using flash/stun/nade? taking cover and flushing me out? flanking me? If I'm in a choke point they won't use a nade but if I'm standing in the middle of an open area with lots of room to dodge, they throw one out on occasion.
In the old MGS, the soldiers were quick to report your location to their HQ. This strikes fear more than any FPSes. In MGS4, they delayed the reporting, and you have unlimited ammo (because of Drebin) -- probably to simplify the game for casuals. These are the 2 breaking points for me.
For close combat, the MGS4 soldiers do use grenades aggressively, especially the FROGs. I have been 'naded and stunned countless times. If they don't do it to you, you may be out of range, undiscovered (they don't know your exact location and are busy fighting the NPCs), or the game limited it (perhaps to make it easier for people to cross the choke point).
There should be a FEAR of getting spotted. Right now it's more of a "oops, my stealth tactic didn't work out. Oh well, time to bust out the G3 and lay em out."
Again, it's very clear that this game had been adapted so it caters towards the shooter fans as much as anything else. However, it's shooting and AI fall well short of top FPS. The best thing it's got going is the production value which outside of the B&B backstories, is quite amazing. That alone is worth a play through.
The combat system is designed such that you could crawl away at any point in time to get back to stealth (Wait for enemy to quiet down). It is not a FPS game for sure. FPS lovers can always go to MGO to enjoy heavy shooting (or being shot it) to their hearts' content. Even then, it is very similar to the "top shooter" CoD4 (scripted, unlimited spawn, no smart AI flanking). It looks to me that Konami wants this game to focus more on battlefield control/management instead of gunslinging.
To complement that goal, it is more difficult/dangerous than regular FPSes when you are flanked in MGS4. The control and control speed are less suitable for quick targeting, the grenades and CQC will knock Snake off his feet, he might lose stamina and faint. Like PMC soldiers, Snake's recovery is slow too. When his stamina gets too low, it can also be difficult to control his aim. If you kill too many enemies, Snake will start to vomit.
If the enemies are as fast and blood thirsty as FPS opponents in Halo and RFOM, Konami may have to redesign the game. Most people would not have time to get back into stealth mid-game. Many will also "die" frequently in the process. I think separating die hard FPS fans into a different game like MGO is a good move. MGO does not have the above design limitations. It also adds customizable skills to suit different people's play style.
