I don't think that I have ever hated civilians in a game more than the ones in this one. They were amusing until I started trying for the Dead on Time badge, at which point their tendency to run directly into your car despite having a fully upgraded horn blaring at all times became rage-inducing (hitting a civilian in that mode subtracts 10 seconds from your time, and I had several runs ended within 1 km of 10 km when two or more civilians charged at my car simultaneously). Immediately after earning the badge, I ran through the main story intentionally hitting every fleeing civilian in revenge. So, congratulations Road of the Dead, you managed to turn me into a flash game psychopath.
I hate this game. The hard badge is broken, I met the requirements earlier and never got the badge. So I just did it again, and before I could take a screenshot to report the missing achievement, the screen froze, and of course since this crap game doesn't save I lost everything. I refuse to do this again, I don't even know if a screenshot would work since there is zero way to prove which difficulty you are playing on once you start the game. I earned the hard badge twice, I want my badge.
Since the wiki for this game no longer seems to exist. I'm curious if anyone knows of (or made themselves) a list of all artifacts. I got all of the artifacts in Crusade and planned to do it for this game too, but I'm not sure how many/which artifacts there are. So far it seems like most artifacts are the ones from Crusade with a few new ones added (and I'd assume some omissions).
For the valkyrie, apply autolife whenever possible, use Natz' and Matt's ultimate attacks whenever possible (try to chain Natz' into Matt's cleaver. his boosted attack coupled with debuffed enemy defense makes a noticable difference in damage dealt), and focus attacks on the valkyrie itself (only attack nukes for obvious reasons, lance to avoid him using the ion cannon, and coolers, which hit hard and inflict obnoxious status effects). Leaving one of the less harmless guns prevents dual nukes from spawning, which greatly increases your odds of success. Hopefully this helps anyone going for the impossible badge, because the picture for it is glorious.
For the zombie hydra boss, try to always have autolife on at least one person (preferably both to avoid dual instant death), and attack the heads evenly until you can finish both off in one turn (I've seen the surviving head go four turns without reviving the other, and have also seen it revive the head one turn after it died, so better to be safe).
For Natz, use thunderbolt during the first section exclusively and get the thunderbolt skill (increases the chances for thunderbolt to cause stun, which is good against the valkyrie which is weak against electric), also get the skill that increases elemental attack damage, the angel skill (randomly casts autolife on Natz), and the immunity skill (and immunity x2 if it shows up, which makes Natz fully immune to all status effects). The other skills are variable, choose whichever you think would be most useful. For stat increases, I increased Matt's magic attack twice (to boost air strike's damage), then attack once, then defence and magical defense twice, then attack (final stats for Matt should be 6 attack, 6 magic attack, 7 defence, 7 magical defense). For Natz, increase magic attack twice, then each stat evenly (final stats were 5 magic attack, 6 defense, 6 magic defense).
Sorry about spamming the comments, but I just beat epic mode, so I wanted to leave a few tips (some of which are covered by one of the top comments, so give credit to them for parts so the strategy). Definitely get the aerial support, secret weapon, cat tamer, and cat warrior skills (use air strike constantly in the first two sections for the first two skills to appear, the summon no legs a few times for those two skills to appear). Get counter for Matt (and counter x2 when it appears), and definitely get survivor if it shows up (it gives Matt a 30% chance of surviving a strong attack with 1 hp, it saved me a lot against the last two bosses).
The earlier bosses are doable with strategy; the guardian can deal crazy damage but is effectively neutered by buffing defense and debuffing the boss when Natz's ultimate heal is available, the golem hits hard but isn't bad once you buff defense, and the sand worm is dangerous if it poisons you but is manageable if killed off within a couple of turns after it respawns its tail. Just focus on using Matt's air strike skill frequently (and choose aerial support and secret weapon skills early) and use autolife during boss battles and you should at least reach the zombie hydra without much trouble.
I was two hits away from finshing off the final boss on epic mode before an eectric spamming satellite dish and a nuke made me almost break my computer (Matt had autolife and full health, but the satellite killed him in one hit and the nuke killed both Matt and Natz). Anyway, epic mode is mainly difficult because the last two bosses can spam instant death attacks; zombie hydra will frequently dual cast death (which seems to ALWAYS kill on epic difficulty), and the valkyrie has lance who can randomly use the ion cannon to wipe you out (and will rarely succumb to seal despite being vulnerable to it) as well as dual nukes, which is basically game over unless you can dish out insane damage in two turns.
How are you supposed to get the achievement for reaching a speed of 275 km/h? Even with a fully upgraded car my speed seems to max out at around 250, which is too low for half of the speed traps and the max speed achievements, anyone have any tips for boosting your speed?
Would Kongregate be able to add a new server that would connect to the game? I'd like to be able to get the badges for this game (and judging by recent comments I'm not alone), it would be ashame if the game was unplayable now just because it's old and the servers are all outdated
