Hey all, I have come up against the same problem as many others with Death Angel - it gets very 'samey' after a short while because there is little variation in the cards. The easiest way around this problem in my opinion is to expand the Terrain cards; with these changed each Location acts anywhere from subtley to dramatically differently.
I've come up with 8 cards per Terrain feature, for a total of 64 cards. Five of the cards are more difficult than the standard (because you know... winning this game is too easy...
), one has no change, and two provide some extra benefits.
I've used the FFG artwork so the game retains the same look and feel as the original. If I had any artistic ability of my own (I have trouble drawing stick figures) then I'd do my own pictures and avoid this paragraph. I must place a gigantic disclaimer here that all copyrights and trade marks remains with FFG . If anyone in the legal department thinks that I'm trying to steal their stuff, then let me know and I'll remove the document.
File can be located [retracted due to legal issues]. It's in PDF format, and will need to be printed on A4 paper. Not too sure how it will go on anything else (the US uses Letter size I believe?) so good luck with it.
I'm also working on expanding a few of the other cards, but in a less imposing way - giving special abilities to all the Space Marines (rather than leaving one in each team to be the main cannon fodder) and possibly even increasing the number of Location cards.
If there are any issues, or if anything needs to be changed, then I'm happy to take suggestions.
