Depends on your weapons, scouts can be killed with ordinary weapons easily, muticanons are perfect. Only go after the larger goids if you have an AX load out and a fairly sturdy build.
I think you need to take a break from the game.
I don't play this thing, it's not a game though, not yet and won't ever be if we allow the devs to get away with this low level of game design. How about an actual threat, that we have civilians to save. You can play pretend all you like but nothing gets affected in the actual gameworld making you entirely disconnected to it.
What's wrong with population numbers going down and TG's attacking us? The OP sounds exciting - when you break it down there's literally nothing to go and save.
