You cannot see your own feet! Space Hulk: Deathwing is one FPS that has a good excuse for not being able to see your own feet. The game is like a Space Marine in Terminator armour simulator. The armour is so big that it is constantly blocking your view of things.
I had to think long and hard as to whether to put the teammates AI as a con. In the end, I decided not to place it as a con. It is true that your AI teammates are not autonomous for most things. So, healing anyone automatically is out. Opening, closing and sealing doors are also out. One thing that they are very good at is killing xenos, at least on the easier difficulty levels. The other thing they are good at is following your orders. Order the apothecary to heal and he will. Order the heavy weapon specialist to seal a door and he will. Order your troops to move back from the horde (ie go to a position) and they will. Although not the smartest teammates in the world, I do think they are one up on the AI of Payday 2.
Within the game, the single-player campaign story is presented via mission briefings, audio dialogue, ships’ logs and psychic vision scenes. Most of the time is spent walking around and beating the bones out of Tyranids though, so if you are after a strong progressing narrative, Space Hulk: Deathwing is NOT for you.
Character upgrades in the single-player campaign are attained by performing certain actions in the game like finding relics, making melee or psychic kills and hacking stuff. At the end of a chapter, you are given fervour points to upgrade your abilities.
In multiplayer and special missions, upgrading is completely different. When you complete or fail missions, experience is awarded. Get enough experience and you level up. Upon levelling up you get renown and a random freebie to upgrade your character. Upgrades can also be bought with the renown you earn.
Ammo is unlimited. It is a good thing too as the hordes of Genestealers just keep coming. The real challenge comes in the form of when to reload your weapon or to use a different attack type.
There are no manual saves for the single-player campaign. Your progress is saved at checkpoints which include activation of the Psygate. In a way, the Psygate activation can be used as a manual save, but there are only a limited number of activations available for each chapter of the campaign. Only your last 9 saves can be reloaded. Your progress is also saved at the end of each chapter.
