I am one of those gamers who has pretty high standards and is very critical and picky about games in general so here are a few things worth mentioning:

The core gameplay is amazing and i would argue one of the best i've experienced, the sound design, the animations and general feel of the guns are fantastic. The enemies respond to your hits and you can see the impact your guns make, like stumbling and dismembering the zeds and not to mention the blood and gore.

That is the main strength of the game by far and is amazing but nearly everything else feels either half-assed, poorly executed or just average.

In no particular order: - It gets repetitive, you will stand in one spot and shoot zeds when they come to you. Even though TWI wants players to run around the map they have failed to make that a viable strategy and there is no incentive to run around the map (besides ammo boxes) so instead it's a strength in numbers, hold this position, buy guns, go back to camping position. - Bosses are in a weird place. And nowhere near as entertaining as the waves before them. You will be shooting a bullet spongy enemy who has little counterplay besides blocking/parrying with a berserker while the others shoot and dodge projectiles, becoming a trivial tank and spank. - In my opinion a decision should have been made to have only one game length, 4, 7 or 10 rounds. 4 feels way too short, 10 is way too long and repetitive. 7 Feels about right but again that's my opinion. It's difficult to find a server combination of difficulty/length with a somewhat small playerbase. I only play HoE difficulty and i often load up the game (which takes a long ass time) just to find out there aren't any HoE games, and no i don't want to play on kfcube or superperktraining. - The game had nearly zero player retention until recently where they added somewhat poorly executed daily/weekly missions. The weekly missions are fun but there aren't many of them. - The zeds don't have an animation when climbing over obstacles and instead they teleport up and down to go over them. - The maps feel like a giant static object where you can't interact or move anything. Oh you want to jump on this car? nope, have an invisible wall. - In general the game doesn't have much personality to it. The characters are ok... the background story basically non existant, you are dropped into a random ass map with a singular purpose of killing zeds and thats it. - General balance issues, but not a huge problem. The Berserker is by far the best perk in the game due to not being reliant on dosh and the medic is close second. Unless some huge changes to gameplay happen or some new mechanics are added this will never change. - Playing the medic feels like a chore and is not fun. You shoot homing darts and occasionally throw a healing grenade... big woop. Point is it doesn't feel satisfying to be the healer of the group and the others often won't even notice what or how well you are doing your job (until someone dies). You shoot a dart and their hp regenerates, it's boring. - The survivalist perk. I don't think they could have done a worse job with that perk and many months have passed yet this perk is still untouched and has no unique identity or anything compelling to give you a reason to even play that perk. Even before the launch of the perk, we had a skill tree preview of the survivalist and the majority did not like it at all and TWI did not do anything to address that. - The community asked for a 'Thanks' voice line added for the characters and TWI added one, but without the voice line and it just displays a THANKS in the chat box. Not an issue but... really?

Ever since early access release TWI has proved to me that they are either incompetent, lack the resources or just don't want to improve these things. But despite all this i'm still playing the game from time to time.
