Gravitee Wars
This is an excellent game, I completed it but then my computer got wiped so I'm playing it again and still loving it. The music is quite boring after a bit, but a good thing is that you can disable the music and still keep the sound effects.
It's a really fun game, a bit like Worms except even better and theres a great range of weapons to use. The medals are good and theres lots of in-game achievements to get, which is a great feature.
I also like the enemy team humour, with references to shows like Peep Show and Red Dwarf. I think this is an almost flawless game - it's addicting and really fun, with many features designed to make this game amazing. Obviously a lot of effort has gone into this.
I really hope there is a sequel which is even greater, which could have more weapons, more team upgrades and more customisation.
The only flaw in this game in my opinion is that the missions are slightly repetetive, though they are still fun.
