We've all seen the last demonstration where around 10 or more Zombies surround the player in that abandoned cottage. And the player didn't have nearly enough ammo to beat them all using his gun.
It's in situations like these that the importance of traps in the game becomes clear. Enemies are more bullet spongy than RE4, not only you will run out of ammo, but the enemies will quickly surround you from every position. So unless you effectively use traps, you're screwed.
to use the traps is what's going to potentially make this part of the game very fun, in my opinion. It will add a whole new and meaty layer of tactics and strategy in the game, and will differentiate it from every other "Horror TPS" out there.
For example, the player in the last demonstration placed those mines under the 2 windows, that wasn't very effective (from a spectator's point of view, at least)... If I was the one playing, I'll have to find "ChokePoints", or a location where a lot of the enemies will be crammed together and place all my traps there so it can take many enemies at once... Like the stairs leading to the basement. Planning like that is probably going to be essential in the game if you want to defeat the enemies, else you will be forced to run away or hide, like the player did in the video.
So far, they revealed the Nails Mine, but they promised that they have a lot different kinds of traps, so I'm interested to see how these different kinds will open up different tactics and strategies, the fact that the Nail Mine is just called "Mine Trap" is making me hopeful the other traps won't just be "Mines", but other unique contraptions. The fact that you can place traps on the floor, walls, or even on enemies backs by sneaking up on them, should also open up a lot of possibilities.
Also, we know that enemies will also place traps... Meaning the levels will be stuffed with these hazards that may kill you if you just sprint around without careful reconnaissance of your surroundings. You can also turn these traps against your foes, like luring a bunch of monsters to fall in their own trap.
Mikami and co. were shouting from the top of their lungs on how Traps are going to be a major feature, not just another part of your inventory. So I'm really hoping they deliver on their promise, because that's what I believe is going to set this game apart from the competition.
The heavy focus on traps remind me of a Playstation classic, a game I loved that rewarded strategic planning and positioning (Although I know TEW won't have similar gameplay, I just wish the focus on traps will be nearly as big)
