Because infinite parts makes the game pointless and pointless up loads of hackers, and ninjadomoman disrupt stops the current recharging of one of the enemies weapons, and I don't know what is happening with episode 3, I have been checking for years.
Way too laggy for the graphics, other than that highly addictive, and will make you very angry feeling like you need to pay money to get good, advice, just don't goto dungeons at level 20 with T7 items thinking it will be easy, there is much more to it, farm pots at lower dungeons like spider den, and snake pit before going to any others, and trade some pots for def ones, they will help a lot.
The portals are impossible without an obscenely large amount of people, and need to be able to continue character, like a 2 time limit in case of a glitch.
Servers need to be better, you aren't using great graphics so it shouldn't be so laggy and have enemies jump around on the screen just to be killed by the 10 that randomly spawned to you.
To lightstriker, there is a part that restores you fully armed back at base called 'retreat', secondly defense turrets are good for protecting an extractor the enemy keeps leaving siege turrets at to stop them from taking the extractor.
Love this game, needs achievements, 5/5, and deadzones are possible, just get enough parts and you can get some from an infected that will spawn there.
I love this game, especially the feature that allows you to make your own level, I've made several lees with it and it worked perfectly. in all,great game!
