If you missed (and I know you did) my forum post here about the release of Bloodmasters, well shame on you!
Bloodmasters is a completely free game, with no spyware, adware or anything that will steal your soul or kill your pets. The entire game is about 45 megs in size, and includes ten (10) maps for you to play on. The game as released, supports Deathmatch, Team Deathmatch, Capture the Flag and Scavenger game modes. It is an independently developed game by a small development team. It uses a custom game engine, and not the Darkspaces engine I mention in my forum post. Bloodmasters is a top down "old school" shooter, so don"t go in expecting a deep gameplay experience here folks. It"s just run"n"gun and blow everyone else away!
The graphics are pretty nicely done, and the game has some very well done lighting and shadow effects for a 50 meg game. The Bloodmasters homepage was just updated as I was typing this up, with news of a patch being worked on, which will fix some bugs and add some new features, and maybe a new map or two. Ah, I just love indie devs.
So go on, download and give it a shot, the game is only 45 megs and is totally free!
