Today I finished off the last two chapters in the single-player campaign of Frontlines: Fuel of War, most of which took place within Moscow. Nothing really new was introduced in these chapters, but the sheer density of enemies and prevalence of things like rocket launchers made it more difficult and slow-going than the previous areas. I took a tank through most of it, but it required a lot of backing off and hiding to allow time for repairs.
Overall, the campaign was pretty good, if short. I haven’t tried the multiplayer part yet though, which will depend on how much time I have, how many other people are around, etc. There are also achievements for completing chapters without dying or within time limits, but I’m not sure if I’ll bother trying for those.
