Does there look to be any new gameplay mechanics/ weapons to look forward to? Or is just new enemies?
From what I've noticed on JP streams as well:
-Damage numbers can be enabled/disabled in the settings
-Air Raider main weapons are drones that mimic his previous arsenal from EDF5.
The air support calls are available most of the time, they cannot be used in cave levels as usual but also in missions set in the timeline where EDF and civilization are both in ruins
-Ranger has a backpack slot for (previously Air Raider's) turrets, grenades and bomb traps. The AA tank is a new vehicle of his.
-Wing Diver also gained an additional item slot for plasma shields and grenades
-Fencer starts with 2 dashes and jumps now and gets giant katanas.
-
You can later obtain an improved Barga with twin shoulder laser cannons with massive range
Oh, EARTH DEFENSE FORCE: IRON RAIN is now on sale on Steam for $15. Why was that the "bad" one again?
I bought it back in January on Steam during a sale. I expected a bad game, not an actual trainwreck however. I review it a while back in another thread.
-Definitively shorter compared to the mainline games: 52 missions in total (EDF2 had 70-ish missions, EDF3 reached exactly 60, EDF4.1 contained nearly 100, and EDF5 had a whooping 110). Although this is a blessing in disguise as the game sucks and you want it to end soon enough.
-NPC allies are utterly useless as they will shoot in the opposite direction where the enemies are located most of the time, and never downwards or upwards. They don't even make good decoys because the aliens and giant insects will often focus on (You), the player, only. I even suspected my allies of killing each other through friendly fire.
-You can easily get stuck in a loop through stuns, frozen status, grabs, etc as unlike in the mainline titles, there are no "invincibility" frames in a short period of time once you're back up on your feet. Poison status from giant scorpions that is eating away your HP was also pretty gay.
-If an enemy corpse is located behind your character model but takes up the space of your entire screen, the game will no longer register the hitboxes of anything you shoot forwards.
-The grinding in Iron Rain is hell. Weapons appear in the inventory upon completing a certain mission (no idea if the rank rating for your personal performance has an influence over the loot) but you need in-game currency, which is divided between money and gems of various colors (blue, yellow or/and red that are dropped by aliens/insects) in order to actually fully unlock said weapons. It's already a problem when B-rank weapons generally need 100k bucks at least while a mission on Hard difficulty awards you at best 30k-40k.
-Increasing your own HP bar also costs money as armor boxes don't appear in this game either.
-Using items like grenades, vehicles or self-healing will penalize you by reducing the total amount of money rewarded.
-Damage output of the weapons was most often garbage against the large HP pool of the enemies. I ended up using the heavy armor PA-Gear class (the "Fencer" class which allows dual-wielding your equipped weapons) in the last row of missions so I could handle the waves upon waves UPON WAVES the game would throw at my face.
-Elite versions of certain enemies are also resistant to a specific type of weapon (grey ants for example can tank laser weapons) meaning the game encourages you even less to experiment unlike in the regular EDFs. As if spending large sums of money to obtain just one weapon wasn't bad enough.
-Probably a problem of the PC port itself but pressing too many keys at once would make my character move towards a certain direction without any further input from the keyboard. Happening to me a few times during the full playthrough.
By comparison, the Yuke learned a lot from their mistakes thus making World Brothers as a good anniversary crossover game.
The Switch port of World Brothers was decent too.
