Meh it's good but this game has glaring issues at difficulties 8-9 and in general :

-90% of weapons being straight up useless
-Most stats on items are hidden or don't work (armor)
-Endgame gameplay is mostly sneaking to the objectives(yes this is fun for like the first 2 hours then it gets quickly annoying)
-Mission variety really isn't a thing
-Mission modifiers make the game less fun overall
-Some ennemies are just not fun to play against and make the lack of weapon viability even worse (chargers, rocket launcher hulks, spewers and bile titans with their weird ass mouth hitbox)
-Most stratagems are garbage too, barrages are litteraly griefing
-Talking about griefing they dedicated a whole stratagem type to this: the sentries, at best they will kill 5 ennemies and get two shot later or will just be a team kill simulator ( props to ems for being decent i guess)
-Robots are way easier than bugs overall at max difficulty and i have no idea why they made bugs this cancerous at higher difficulties

But yeah the game is good could be better if they fixed all this shit tho.
