Maybe we should just have a thread for game bundles and sales if this becomes more frequent.
Anyway, not really a bundle, but some codes to buy directly from the developer's sites:
http://www.showmethegames.com/sales.phpFrozen Synapse is on there in case anyone missed it. Again, my name is ProfessorPaul1290 on the UK1 server. Remember that this comes with two copies.
http://www.youtube.com/watch?v=vVGu_ydmwm8&hd=1AI War: Fleet Command is on there as well, which I've mentioned before as one of my favorite strategy games next to. There's a demo on Arcen's site which I highly recommend at least trying if you like strategy games at all.
http://www.youtube.com/watch?v=KO125KMoVjE&hd=1Evochron Mercenary is there as well, which I recommend at least checking out the demo for if you're looking for a space sim. It's somewhat like Freelancer except with Newtonian physics and combat similar to I-War 2.
http://www.youtube.com/watch?v=lW6vHgRgTe8&hd=1Space Pirates and Zombies, Gratuitous Space Battles, and a few others are on there as well.
Keep in mind these are codes for purchasing directly from the developer's sites so if purchasing from that dev's site lets you register it on Steam, Impulse, or whatever then that will work as it normally would.
